JAVA backend? Niginx proxy?
Look at the nginx log
Can’t you Google it first and think about it yourself before asking questions? You're really delaying others from browsing important information! shame on you
No information at all. . . How to judge
The background may have been down
The Java background monitored by nginx is not started, or the background hangs.
Brother, it’s obviously 502
They are all pushed to Google Now. If needed, I can help you fix Java and Nginx for many years
Look directly at your background output log
This can only mean that your background is down
