502 Bad Gateway on nginx

Help
1

I am receiving an error 502 - Bad Gateway. I have googled this for a while now and checked multiple config files. I do see the Fav icon on my browser tab & nginx/1.18.0 (Ubuntu) is displayed on the page.

i followed this guide:

Follow the offical guide instead https://docs.librenms.org/Installation/Install-LibreNMS/

while i followed a different guide & could have followed this one; you’re reply is not helpful.

I would prefer to troubleshoot the setup I have been working on rather than start over with a different guide.

So far, I had database connection issues. I have fixed those and have the database connected. Then I ran the validate.php script. there were several errors. I rectified all of those. Still, I experience a 502 error. I am no stranger to Linux or working withing the terminal. I am not looking for an answer. I am looking for a place to start because I have not had success yet. I will go over the nginx configuration and perhaps permissions but after that I will be at a loss.

thanks :slight_smile:

I would chech the nginx errot log and see what it is failing on. Typically the 502 bad gateway means something in nginx or fpm failed.

I actually just now located the problem and came here to post an update. There existed a type error in the run path within the nginx/conf.d/librenms.conf file. Fixed the error and it loaded right up.

Thanks for the help!!
