Hi @hSaria here is my gunicorn config as per readthedocs.io guide

command = '/usr/bin/gunicorn'
pythonpath = '/opt/netbox/netbox'
bind = '127.0.0.1:8001'
workers = 3
user = 'www-data'
max_requests = 5000
max_requests_jitter = 500

I understand this could not be a direct bug with Netbox @jeremystretch but if I can do literally everything else except adding sites via the "add site" button or edit sites added via import do you think the problem could be related to the installation method(which it is also provided by your docs) or even Layer 8?

BTW: I used the template in https://github.com/digitalocean/netbox/issues/new/choose

Adding timeout to gunicorn did the trick

timeout = 60
