404 page not found

Troubleshooting
1

Hello,

I currently have a CheckMK Omd server running version 2.1.0p12 on a Debian server with version 5.10.140-1.
After performing an update (using the “apt-get upgrade” command) and restarting the machine, I encountered an issue.
The web interface displays a “404 Page not found” error, preventing me from logging in.

When I check the status of my OMD using the “omd status” command, here’s what I get:

  • agent-receiver: running
  • mkeventd: running
  • liveproxyd: running
  • mknotifyd: running
  • rrdcached: running
  • cmc: running
  • apache: running
  • dcd: running
  • redis: running
  • crontab: running

The overall state is indicated as “running.” All my Apache settings appear to be correct.

Does anyone have an idea of where this issue might be coming from?

Thank you in advance.

If anyone has an idea of ​​my problem, would it be possible to make a backup of my CheckMK via SSH before a complete reinstallation?

Hi @susanoo,

that’s strange, normally an apt update && apt upgrade shouldn’t affect your Checkmk installation at all.
Easiest question first. Did you restart your server again and does the issue still persists?

Another troubleshooting starting point would be to check the web.log of your Checkmk. ~/var/log/web.log

Looking forward to your reply.

Hi, maybe these two links may help you:

Especially the command “omd update-apache-config”.
