What does it mean that there is a 502 bad gateway in online booking?

Frequent occurrence I think that since it is so difficult on the Internet and there are always mistakes, why not bring forward the pre-sale period of the window? It's 4 days different from the Internet, obviously you have to buy it online, you have to buy it online, and it has been wrong, it's ridiculous, it's an excuse for those tickets that go through the back door, and then there are no tickets to say that they are sold out online, and they didn't always line up in the middle of the night, and they opened tickets at that point, and they didn't have tickets anymore, causing public outrage, and now it's okay, people can say that they are sold out online, but only we know that they can't buy it at all.

I thought it was just me. So I'll wait a little while and see**. Boring under the ship.

It turns out that so many friends have met. Grass. What the hell?

It's so much trouble to get a car. It's better to go to the queue before. I get up at 5 a.m.

Waiting for the start of 6 o'clock. I thought I could get ahead of the curve. Who knows it's always progress.

You can still register at 6. As a result, the ticket purchase has been refreshed. It's just that it keeps saying an error message.

nnd。It's almost 8 o'clock by now. As a result, I can't even get into which page to land on now.

My poor go to bed early, it's better to sleep more.

That's the case with me.

I want to die of refreshment, I get up at 6 o'clock, and I keep logging in here 502 bad gateway and I thought it was just me.

It's so difficult to live as a Chinese.

If you want to go home and buy a train ticket, it's like fighting.

The governance of the country has reached this point, and the public utilities are so bad.

Disgusting not disgusting!

I've been staying up for 3 days in a row, and I'll give you the most sincere advice, if you want to book a ticket, just keep dialing **, online booking is not reliable. Even if you can see the ticket, every time you submit the order, it will be stuck. It's still **reliable.,Although I hit hundreds of ** in 3 days.**, but there are always so many passes.

I can also book a ticket, but I didn't ask for it, I want to book a sleeper, and now there are no standing tickets. Don't worry about regrets.

face:60] Me too, the old 502 bad gateway, back and forth for more than 1 hour, go in many times, look at a lot of tickets, a little booking can't open or exit, haha! I'm going to reinstall the operating system and order it again tomorrow.

Me too, I looked at it at five o'clock in the morning, I couldn't go up, I couldn't buy it, I tossed it for half an hour at 6 o'clock, the ticket I wanted hasn't been released, just now I logged in and showed that 502 gateways were broken, and now it shows that the server is busy, I'm going to crash, please can the Ministry of Railways do something practical.

At first I thought it was a connection issue and the refresh didn't work. Alas, sad! Hurry!

I started logging in at 6 o'clock in the morning yesterday, but I couldn't log in, and finally landed on the 12 more, and it showed that there were too many reservations, which made me depressed later

Yes, what's going on today, these words have been appearing frequently, booking tickets online while typing**, hold on...

It's all the same, I can't book it.

I've been typing for more than an hour and still can't get in.,I thought it was a problem with my computer.,It's really embarrassing!

Going to die, going to die! Hate NND502!

What's the matter, I logged in at 6 o'clock in the morning and it showed no ticket, and now I can't log in, and I always get a 502 error.

That's a lot. Mine is the same, I thought it was a computer problem, the computer was restarted, the Ministry of Railways is really shitty, making so much money is squandered.

It is recommended that the Minister of Railways take the blame and resign, and those who are capable are competent.

Now I can't even see the verification code.

The Ministry of Railways of the dog, iron your mother.

How can this be, Iron Boss, you have made so many people suffer! Hurry up and recover!

Online ticketing has harmed a large number of ordinary people. The network is so imperfect, what is the online booking of tickets, in order to book a busy online for three days, where are these tickets?

I haven't been able to log in to book tickets online, and I've been dying since 5:50, and I can't book tickets. Plane tickets can't be booked, and train tickets are bullying.

It's over, I estimate that I have to drive 1300 kilometers back to my mother-in-law's house today, and my sister's is worse than the era of scalpers. . .

**And the Internet is deceiving, hahahahahaha!!

bad gateway: Wrong gateway, invalid gateway; In the Internet, it represents a network error that manifests itself in the feedback given by a web browser.

Bad gateway error: In simple terms, 502 is the wrong gateway with bad gateway type.

2. The cause of the error: the connection timed out. We send a request to the server This error occurs because the server is currently connected to too many links, which makes the server unable to respond normally.

3. The way to rescue:

Basic Refresh: Just click Refresh or use the F5 shortcut. It is possible that a basic refresh simply refetches data from the local hard drive to the browser, and does not necessarily re-make the request to the server.

Most users refresh like this many times, and when they encounter a 502 error, it has no effect.

Refresh from the server: If you re-click directly on the link to the web page you want to view, you will notice that it appears"502 bad gateway"The page with the error message can be viewed again after clicking the link.

502badgateway must first find the path configured in nginx.

Then find the error log file where nginx is located to see the specific cause.

If it is a problem with the configuration of the client browser, taking the 360 browser as an example, the 502badgateway may be caused by setting the code **.

Once you've canceled your browser**, refresh it and you're ready to go.

502badgateway is an error message that does not mean that the upstream server is down (no response gateway), but rather that the upstream server and gateway do not agree to exchange data.

Given that the Internet Protocol is quite clear, it often means that one or two machines have been incorrectly or incompletely programmed.

It's that the railway company won't let you buy the most affordable ticket.

12306 Ministry of Railways Server Center, the interface is ugly and something is registered, and humanity is either 502 bad gateway, or there is no ticket. Why is it gone if it is not sold? I can't get in.
