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.
Does your router have an app or way of letting you remotely see if the server is even showing on your home network?? It could be a physical disconnect or Ethernet port failure, or NIC failure maybe? A reboot wouldn’t help if the issue was related to something like that.
Edit: Actually, re-read your post and thinking about this again, what I said wouldn’t make sense…
You could have some sort of corruption causing an error in the appdata, preventing it from running. Might be a RAM issue.
It has a network connection, I am able to get to the nginx error, the services themselves are down. What’s really weird is everything is down, even SSH.
I edited my original post right when you replied, my bad.
I dunno if you can do that much remotely, honestly. I kinda feel like something might have corrupted? What kinda system are you using? Any more details you can provide?
