Check the nginx log for more information on error
also check which version of php is running with below command
ps aux | grep php

I think I found the log file.
[email protected] :/opt/librenms# cat /var/log/nginx/error.log
2022/10/27 07:46:29 [crit] 46732#46732: *18 connect() to unix:/run/php-fpm-librenms.sock failed (2: No such file or directory) while connecting to upstream, client: 10.x.x.x, server: , request: “GET / HTTP/1.1”, upstream: “fastcgi://unix:/run/php-fpm-librenms.sock:”, host: “10.x.x.x”
sudo service php-fpm status

OK I am back online again.
Solution was to edit;
/etc/php/8.1/fpm/pool.d/librenms.conf
Change [www]
to [librenms]
:
Change user
and group
to “librenms”:
user = librenms
group = librenms
Change `listen` to a unique name:
listen = /run/php-fpm-librenms.sock
Then restart:
systemctl restart nginx
systemctl restart php8.1-fpm
Thanks for your help guys.
cheers,
system
