Strange connectivity issues, can ping, SMB but no webGUI

I have a strange connectivity issue with TN Scale that I cannot solve (latest version). Everything was all working on this system for months but now I cannot access the Web GUI.

The strange thing is I can still ping, SSH in, SMB shares still work and the VMs are also running. When SSH’d in to TN I am also able to ping back to my PC. However the Web GUI just will not load. It also gets stranger, one of the TN VMs has docker running - I can ssh into this VM and see all my containers are running correctly. However I cannot connect to the web interfaces of these containers either, portainer, plex etc.

So I am starting to think that HTTP traffic is not getting through for some reason. My docker containers are listening on all sorts of different ports so it isn’t just a 80/443 problem. I currently just have a simple bridge with fixed IP (used by the VM) and no VLANs. I have tried various network config changes, adding VLANs, added a different Intel NIC, but still the same issue.

Whilst trying different networking config, I was able to connect to the Web GUI for a short time - I thought everything was fixed then all HTTP connectivity dropped again after about 5 mins without me making any changes.

I have tried restarting the middleware, but that didn’t seem to change anything. I am all out of ideas now, not sure if this is a networking issue or a TN issues.

Any help would be appreciated.

For anyone that has this issue in the future I found the issue. It was after my Mac had updated to OSX Sequoia. It seems to have some inbuilt feature that blocks local network access until you approve it. Kind of strange that I was getting intermittant connectivity rather than all out block - clearly doesn’t work very well. Anyway, after I restarted and reloaded my browser it finally prompted to allow local local network access. Once approved all is working as expected.
