I think I made a progress. Namely I stumbled upon this post 

https://github.com/librenms/librenms/issues/3525

Replacing 

 location / {
   try_files $uri $uri/ @librenms;
    }

with 

 location / {
   try_files $uri $uri/ /index.php;
    }

Did the trick for me. I would still appreciate if people who are running
LibreNMS in production can explain me what am I doing wrong.
