Help

I just upgraded my Librenms VM to Ubuntu 18. I had the database issue I was able to fix, but am unable to reach the WebUI currently, I get this error (in Chrome):

ERR_CONNECTION_REFUSED

Here is ./validate.php:

librenms@librenms:~$ ./validate.php

	Check the cron job to make sure it is running and using discovery-wrapper.py

Any help would be appreciated…

What is the result of running crontab -l under the librenms account?

The discovery has resolved itself, see the new output. Also below is the crontab output if you still want it:

librenms@librenms:~$ ./validate.php

Did you check this Upgrade ubuntu 16.04 to 18.04 - DB Issue

Sounds like nginx/apache configuration issue, check the service status

Got it figured out, it was an nginx config issue…

You should describe the resolution for anyone who has a similar issue and comes to this post… :slightly_smiling_face:

OK, here’s what I did:

  1. Update Ubuntu 16 until fully updated.

  2. Run ‘do-release-upgrade’ to update to Ubuntu 18.04.2

  3. After this was completed I ran ‘validate.php’ & ‘daily.sh’ and saw that I had the database issues. Also could not connect tot he WebUI. This is when I posted here about it.

  4. Found this thread, and did what Bob_Puts suggested in his post: https://community.librenms.org/t/upgrade-ubuntu-16-04-to-18-04-db-issue/7120/9?u=gun_runner

  5. Also ‘nano /etc/nginx/conf.d/librenms.conf’ to change the fpm.sock to 7.2 as well as the re-setting the server_name.

Works now after that…
