SABnzbd only accessible from localhost

[realisticsqrl]

I'm running SABnzbd on Ubuntu and it works perfectly on localhost.
But when I try to access the web interface from another device on the same network, the page is unreachable.
I have read some topics on this forum and tried some suggestions, but none of these seem to be the issue...

First of all, my SABnzbd Host & Port are set to the following:
SABnzbd Host: 0.0.0.0
SABnzbd Port: 8090
HTTPS disabled

On my Ubuntu device, I can reach the web interface from all following addresses:
localhost:8090
127.0.0.1:8090
192.168.0.103:8090

When I try to access 192.168.0.103:8090 from another device on the same network, the page is unreachable.
I have tried this on several Windows laptops and Android phones.

I have ufw enabled, and added a rule to allow access from anywhere:

Code: Select all

Status: active

To                         Action      From
--                         ------      ----      
8090                       ALLOW       Anywhere   

Even with ufw disabled, the issue isn't resolved, so most likely not a firewall issue.

Also, I have checked that my device is listening on port 8090:

Code: Select all

tcp        0      0 0.0.0.0:8090            0.0.0.0:*               LISTEN      off (0.00/0/0)

Any suggestions to solve this problem would be very welcome

Does ufw do any logging?
Can your Windows/Android devices access another service on your Ubuntu? Can they ping the Ubuntu machine?

Just throwing this out there: are the devices you’re trying to reach SAB from all connected wirelessly? Are you using any sort of AP isolation in your router?

I have just searched my logs for the port number and local IP of connecting device, which returned the following 2 lines several times:

And yes, I use my Android phone to access other services on my ubuntu machine, such as Sonarr, Radarr, Plex,...

I have tested my devices both with wireless and wired connection, so I think that shouldn't be the issue.
Just checked my router settings, AP isolation was and still is turned off.
Thanks for the ideas!

I'm not a UFW user, so you have to interpret that yourself. And compare with when accessing Sonarr etc.
