Hi - I did a network change on my unraid box yesterday to make it use an SFP+ port as default

I did have some grief getting DNS to update and therefore connecting thge box to Unraid.net - sorted that but all of my bridge dockers now.... while they are running perfectly fine if I go to the IP and port manually they are running and working fine

However if I click any of them from the Unraid UI and Click open WebUI nothing happens at all

I get this in Edge Developer Mode

Uncaught SyntaxError: Failed to execute 'open' on 'Window': Unable to open a window with invalid URL 'http://[ip]:[port:8971]/'.

at HTMLAnchorElement.action (docker.js?v=1749406518:7:129)

at HTMLDocument.dispatch (dynamix.js?v=1758227634:5:40035)

at v.handle (dynamix.js?v=1758227634:5:38006)

Any idea what the cause of that maybe? Working fine yesterday before the change to Eth1 instead of Eth0

Pi Hole is the only UI I can get to as that is running in HOST mode

Thanks for any tips

Fixed it - had to move this back to br0 rather than br1 - dont exactly know why but that fixed it for me straight away

@kiteboy I'm having the same exact problem - recently installed a new network card and the WebUI link doesn't work in Docker containers anymore. Typing in the URL of the container though does confirm the container is working. I am getting the same error message in developer mode in Edge (also doesn't work in Firefox or Chrome). Can you elaborate on how you fixed it? Not sure I understand that you had to move this back to br0 rather than br1?

Never mind I figured it out. Under Interface Rules in Network Settings, I had to move my new dual port network card so that they were assigned to interfaces eth0 and eth1, and the previous internal network port as eth2 (it was previously eth0). I also made sure that the port that was connected to the internet was assigned to eth0. Once I did that, I enabled bridging on eth0 and made sure the bridging members of br0 was set to eth0. Once I did that, the WebUI menu option in the docker containers started to work and I was no longer getting the errors in the Edge developer window. Thanks for the tip that led me to how to fix this.
