Hmm, I understood at first, the file I uploaded was not running and only the server's login screen was displayed.
Sorry for the misunderstanding.
I checked the contents again, and roughly what kind of error was confirmed.
But this is the first time I see the above error.
I didn't build this program so I don't know how to fix the above error.
Tomcat seems to work, but I don't know why it doesn't communicate.
However, I saw the manual in this file and made it a little differently.
I need the original bt.cn, but I don't use it.
nginx, php, and mysql are all directly installed in a different way.
The rest are the same.
My published file works fine, but I don't know why your server doesn't.
Sorry for not being able to help.
After connecting to the server by opening a program such as winscp, check the log files of each server program (all of the /opt/server folder).
