What s wrong with FTP not connecting?

331 - This status is displayed after the client sends the username. The status is displayed regardless of whether the user name provided is a valid account in the system.

Common FTP status** and their causes.

150 - FTP uses two ports: 21 for sending commands and 20 for sending data. A status of 150 indicates that the server is ready to open a new connection on port 20, sending some data.

226 - The command opens a data connection on port 20 to perform an operation, such as transferring a file. The operation completed successfully and the data connection was closed.

230 - The status is displayed after the client sends the correct password. It indicates that the user has successfully logged in.

331 - This status is displayed after the client sends the username. The status is displayed regardless of whether the user name provided is a valid account in the system.

426 - The command opens a data connection to perform an operation, but the operation has been canceled and the data connection has been closed.

530 - The status indicates that the user can't sign in because the username and password combination is invalid. If you sign in with a user account, you may have typed the wrong username or password, or you may choose to allow only anonymous access. If you sign in with an anonymous account, the configuration of the IIS may deny anonymous access.

550 - The command was not executed because the specified file was not available. For example, the file you want to get doesn't exist, or you try to put the file into a directory that you don't have write access to.

Consider the following reasons:

1. The firewall is blocked.

2. There is no permission to view the content.

3. The NMS shields the FTP port.

The default is PASV mode, because of the settings of the server firewall, the client cannot use PASV mode, and it is normal to set the PASV mode in the settings to empty.

FTP connection to a server may fail due to the following reasons:

1. FTP connection to the server fails due to network failure.

Sometimes, it may be due to a problem with the local network of the server or computer, which causes the FTP connection to the server to fail. You can check your browser to see if the web test is a network issue.

2. The server is down, crashing, restarting, etc.

When we rent a server, we will check the access speed and stability of the server. The server has the right machine, crashes, restarts, etc., which will not only cause the FIP to fail to connect to the server, but also directly lead to the inability to operate normally, which will affect the optimization of the ranking and user experience. If this happens, contact the server provider as soon as possible to resolve it.

3. If there is a problem with the firewall setting and the server connection fails, check whether our firewall setting checks the "PASV mode", if it is checked, then it will be canceled, and then try to reconnect.

4. If there is a problem with the FTP software, the connection server failsSometimes we forget to update the software in time, so the version of the FTP software used is too low or is deactivated, or there is a problem with the software. At this point, we can delete the existing software and then reinstall it.

5. Too many times to connect to the server in a short period of time.

Maybe because the FTP connection speed is a little slow, we are in a hurry to wait, so we keep clicking the connection button, resulting in too many connections in a short period of time and the connection fails.

6. The server is blocked by the ISP and the FTP connection to the server fails, and the server can be tested by using the ** server.

7. The rented server background is closed.

If the above situations are ruled out, then it is likely that the backend of the server we rented has been shut down, and we need to connect to the server provider to review and modify.

There are many reasons why FTP fails to connect to a server, and the above are the most common cases. In order to ensure the normal operation of the first place, when the FTP server fails, the cause should be checked and solved in time.

Summary. Select Windows Firewall on or off on the left to enter.

Why can't I get in the FTP address?

Dear, because the firewall is not turned off.

How do I turn it off? Open the control panel on your computer and select the large icon on the right.

Select Windows Firewall on or off on the left to enter.

Select Disable Firewall, and click OK to disable the firewall.

What is the big icon?

Wouldn't it be a problem to turn off the firewall? There is also what type of network firewall to turn off.

It's just a firewall.

It's because of a problem with your address.

The ftp address is the IP address of xshel, right? That's right.

If you notice interruptions in the upload process, there could be four reasons:

1.You should make sure that the IP settings of the server are correct, whether the port is correct, then that the FTP service of the server is started, and finally that you have access to the server and the port (the firewalls on both sides are on).

2.One is that the server provider has set up FTP security protection, that is, if you do not operate the FTP tool for 10 minutes when connecting to FTP, or there is no monitoring, then it will be automatically interrupted, which can prevent people from maliciously entering your space due to your carelessness.

3.Another reason may be your FTP settings, you can try to disable PASV passive mode.

4.It could also be that the server is crowded.

With IE accessibility, there is no problem with FTP erection, and now there should be two reasons:

1. You can set the "default web client" on the FTP server, you can see if the settings are correct.

2. Whether the connection parameters of the client flashfxp are set incorrectly (because I have not used this software, I can't tell you the specific setting method).

Hope it helps.

1 6 step by step reading.

Check whether the username and password are correct, FTP needs to have the username and password assigned by the FTP server to establish a connection with the server, if the username and password are incorrect, the connection cannot be established with it.

2 6 Check whether the FTP server address is correct, the FTP server address can be an IP address or a domain name address, depending on the actual FTP server configuration. Make sure that the domain name or IP address of the FTP server is correct and can be connected. Its connectivity can be tested using the ping command, which is as follows:

CDN-Borui Hongyuan network application performance monitoring to ensure user experience.

AD 3 6 Check whether the port number is correct, the default port of the FTP server is 22, if the FTP server modifies the default port number, the client also needs to modify the corresponding port number.

Server trial Free filing Sufficient bandwidth **Lower than peers.

AD 4 6 Check whether the FTP protocol corresponds to the server protocol. In addition to FTP, file transfer protocols such as XFTP are also available, so make sure that the protocol between the client and the server is the same. As shown in Fig.

You try to use 8uftp software, after opening 8u, "File ——- Site Management - New Site", fill in the address and user name.

If your IP address and username and password are correct, the server is not able to connect.

You first ping the IP on the server, see if you can ping through, if you can ping through, check whether the port of the ftp upload tool is 21, if it is still not linked, there are several situations, one is that the server is restarted or not started; Second, port 21 on the server is closed; Third, the local network is not smooth.

You can get in touch with your server or web hosting provider and ask them to assist you with your FTP link.

There may be a network problem, some private server addresses on the Internet can not be logged in, you can go to the same network as the server to try to log in, if you can, it is your network problem.

See if your IP is static or not

2. Open and find "Site" in the upper left corner.

3. Open and find "Site Manager".

4. Click "New Site" after clicking.

5. After opening, name the site name.

6. Then fill in the IP address of the server as required. FTP account, FTP password.

7. After filling in, pay attention to the port. Otherwise, you won't be able to connect. Finally, just apply the link.

Reasons and solutions for FTP can't log in:

One. If any user is unable to log in, please check the following to resolve the issue

1.Is it caused by you closing the port used by FTP?

FTP requires ports 20 and 21 by default, however, a large number of users use the office.

Area network. As a result, a large number of dynamic terminals ranging from 1024 to 6000 are also used on the server.

port, you cannot prohibit any port used by FTP, otherwise it will cause FTP

It doesn't work properly and PASV mode doesn't work if you have to throttle the end for special reasons.

Run C: InetPub AdminScripts Set msftpsvc PassivePortrange"5500-5700"

You can set the port range to 5500-5700

Causing you to remove the PASV mode to run, it is caused by the firewall if you want to turn it on.

With Windows Firewall, Reference:

It can be run directly.

c:\inetpub\adminscripts\

set /msftpsvc/passiveportrange "5500-5700"

You can set the port range to 5500-5700, and then you can let the data center in the firewall.

The 5500-5700 port segment solves this problem.

FTP upload is slow:

FTP software does not have a speed limit, and it is not possible to do speed limiting, therefore, causing this problem.

The only reason for this is the network impact, which is possible in the following ways:

1).The computer room where your server is located throttles the network speed.

2).The egress bandwidth of the computer room where your server is located has limited bandwidth, which affects the upload speed.

3).Your own computer is located on a slow network, such as Netcom uploaded to a telecom server.

It's going to be slow. The FTP software can connect, but the browser can't

FTP software can be connected, it means that the server is normal, IE can not be connected, it is likely that your computer is intranet, IE does not use PASV to connect, or it may be caused by the restriction of ports on the server, please refer to the first part of this document.

1.It may be caused by an internet connection. Ping or directly telnet connection to the server port 21 can be.

2.It is possible that you are using passive mode, and in some network situations, if you use passive mode, you will not be able to connect to the space with FTP, so you need to change the connection mode to active mode in the FTP tool.

Reasons and solutions for FTP can't log in:

One. If any user is unable to log in, please check the following to resolve the issue

1.There is no port used by FTP closed.

2.Is it caused by FTP whether it is started or not.

3.It is not caused by you manually modifying the home directory of FTP.

Select [Home Directory] (in the local path, you should look at the content of this "C: InetPub FTProot", if you see something other than this, please change it back to "C: InetPub FTPROOT" and click OK to restore the original default FTP home directory setting).

4.Is it caused by the deletion of this directory "c: inetpub ftproot" on the server.

When the directory "c: inetpub ftproot" is deleted on the server, it will cause FTP to be none.

Law login. Follow here to solve:

1) Please check the server to make sure that the directory "C: inetpub ftproot" exists?

If you delete this directory by mistake, you need to manually re-create this directory, 2) the permissions of this directory are automatically set when you install the control terminal. Normally, this.

The directory needs to be read by everyone. If you don't have this permission, ** on it.
