FTP login failed 10

Is it blocked by the firewall, you uninstall the firewall and try it.

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.

The reason why the computer cannot log in to the FTP site may be due to the incorrect firewall settings, or the FTP option of the browser may be incorrectly set. Here's how to deal with it:

The first step is to check whether the firewall software settings on the computer are correct, whether the default firewall of the Windows system has port 21 open, or whether the computer has firewall software installed, such as the personal firewall of the terminal star, which must support FTP port 21 before it can be used.

Step 2: Check whether the FTP software has removed the passive mode, the default mode is sufficient, you must manually select the passive mode to remove it before you can log in normally, the way is as follows.

1. Use IE login method:"tools"-->"Internet Options"-->"Advanced"tab, scroll down, you can see "Use FTP passive mode" and remove the previous checkmark.

2. The same is true for using FTP client tools, you should remove the checkmark in front of passive mode and PASV.

cuteftp:edit ->setting ->connection ->firewall ->pasv mode or file ->site manager, select site ->edit ->use pasv mode on the left.

3、flashget：

Tools -> Options -> Server -> Direct Connection -> PASV mode.

4、flashfxp：

Options-> Preferences ->** Firewall Identity -> Use Passive Mode or Site Management -> Corresponding Site -> Options -> Use Passive Mode or Quick Connect -> Toggle -> Use Passive Mode.

The other party's server must be enabled with the relevant telnet or FTP service. Otherwise, even if your command is correct, you won't be able to connect to the other party's server.

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.

If you open a new space, FTP does not have write permissions by default

This is caused by you not clicking the setting ftp in the automatic setting controlled end, please click again in the start, automatic setting controlled terminal.

After a while, you can't log in to FTP, you can log in after changing your FTP password:

This is caused by the password policy in the local security policy on the server, which will be caused by locking if you set the wrong password, if you want to enable this setting, please set it to 500 errors before locking.

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.

FTP can log in, but the reason for not uploading and the solution:

If you try to upload content to a directory that is not allowed, you will be prompted that the upload failed.

After you FTP logs in, the only directories you are allowed to write to are:

ftp username web".

ftp username db".

After you FTP login, the directories that are not allowed to be written are:

ftp username """

ftp username log".

Your space has run out.

In this case, you'll need to delete some of the files and make room for them before you can upload new files.

3.In the panel of the web host, you have set "Turn off the write function".

4.A small number of users are in the intranet, and when uploading files, the upload fails due to network restrictions. This situation can only be solved if the user changes the network to upload.

ftp can log in, but it can't delete files Reasons and solutions:

Caused by a locked file. (e.g. access databases are often locked,).

Solution: After stopping the virtual host for a while, it will be unlocked, so that you can delete this file, if you stop the virtual host can not be unlocked, you can unlock this file in the management area, where the virtual host is managed, **The pool where the virtual host is located.

It is possible that the file is used and has not been released, **a process.

I've been working backwards for a long time.,The link 21 port can't be used.,But the other ports are fine.,After ruling out all possibilities,Finally determined a point.,It's a problem with Unicom optical modem.,The optical cat is Sichuan Tianyi company.,Their optical modem estimates that the factory restricts the login of the remote server's 21 port; There is no problem in contacting Unicom to change to a new optical modem.
