unable to access on LAN

Recently I am unable to access sab via its ip:port. I get an External internet access denied (or Access denied) and the only way i can access it now is by setting the inet_exposure value = 5 and creating a local username/password.

Sab is running on my synology in a docker container and the device (wifi) I am trying to access it from is on the same network as the synology (hardwired).

Docker Network:

Name: synobridge
Subnet: 172.20.0.0/16
IP Range: 172.20.0.0/16
Gateway: 172.20.0.1
IPv6: disabled
IP Masquerade: network:enabled
Containers: radarr/overseerr/sonarr/sabnzbd/tautulli

I have ran the logging with debug and it is showing me my device is attempting to access sab via an IPv6 address, but im not sure why that is because ipv6 is disabled on the network we are on, and it is disabled on the docker container network as well.

Im pretty sure the default host when I first set this up was :: and the port was 8080. But im not sure what the external access was when I initially configured this.

Possible values are:

0 = No access (default)
1 = Add NZB files
2 = API (no Config)
3 = Full API
4 = Full Web interface
5 = Full Web interface - Only external access requires login

Im not sure why sab is not detecting the network I am on as local (192.168.1.xxx) which is the same network the synology is on as well.
