have a Debian server running fusionPBX, I installed it using this official script. It uses nginx to host the application, I tried adding another server (Django) in the config file of nginx to support another server that's running on the same machine. Still, I can't access the Django server.
I tried opening port 8000 using the command sudo ufw allow 8000
When I use Nmap from another machine to this FusionPBX server I do see the ports.
Even if I start the server using the normal command python manage.py runserver 0.0.0.0:8000 or python manage.py runserver 127.0.0.1:8000 It doesn't work.
In Ubuntu, all I have to do is sudo ufw allow 8000 and then python manage.py runserver 0.0.0.0:8000 and it works as expected.
python manage.py runserver 0.0.0.0:8000 this is how we start a django server, where 0.0.0.0 is the IP and 8000 is the port. just in case anyone is confused
My Nginx config
The block that I added
Is FusionPBX blocking the connection in some way?
I don't know what I'm missing, any help is appreciated.
Things I Tried:
so I tried opening the port using iptables, here is what I did
The Outputs
I tried opening port 8000 using the command sudo ufw allow 8000
