Nginx 502, ssh not working. (sh.itjust.works)

I am currently out of town, and my server went down. All my services go through nginx, and suddenly started giving error 502. My SSH won't let me in. I had my sister reboot the server, and it still doesn't work. I apologize for the lack of details, but that is all I know, and I can't access logs. I've cleared cache, and used a VPN in case fail2ban got me. I recently got a tp link router, so it could be something with that, but it was working for a while. I will have her do another reboot, and if that doesn't work I will have her power off and unplug the server in case it was hacked.

Edit: I have absolutely no clue why, but it works now. I literally did nothing. As far as I know, my sister hasn't touched it today. It just started working. Computers, man...

Edit 2: Actually she said she did something. Not sure what, but it works now.

502 means the app is broken. For example, if it were Flask python, it would be raising an exception (e.g. divide by zero). If this is happening to many services or apps simultaneously, it is concerning. Turning it off sounds wise at this point.

Yeah, I would think docker is broken, but that wouldn't explain the SSH, which is bare metal and doesn't go through nginx.
