The backend of the company website is written in Java. When accessing it, I get 502 Bad Gateway. What is the reason? Only I am visiting

I am the only Java technician in the company, and Party B has not yet delivered the project, so I cannot see all the data in the background

    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

    The Java background monitored by nginx is not started, or the background hangs.

    They are all pushed to Google Now. If needed, I can help you fix Java and Nginx for many years

    This can only mean that your background is down
