502 Bad Gateway nginx/1.16.1 CentOS

Hi Guys, I’m going to come across really clueless here so I apologize in advance.

Came in this morning to an error on my server (Whoops, looks like something went wrong. Check your librenms.log)

Managed to get past that somehow with lots of Googling and pasting random commands in. But now I get the 502 error and the two posts I’ve seen aren’t really helping me.

Anyone got any ideas where I should look for the cause? Results of validate.php below.

[[email protected] ~]$ ./validate.php

Component Version
LibreNMS 21.1.0
DB Schema 2020_11_02_164331_add_powerstate_enum_to_vminfo (191)
PHP 7.4.15
Python 3.6.8
MySQL 5.5.68-MariaDB
RRDTool 1.4.8
SNMP NET-SNMP 5.7.2

====================================

[OK] Composer Version: 2.0.9
[OK] Dependencies up-to-date.
[OK] Database connection successful
[OK] Database schema correct

Maybe check your nginx config?
