VM on br0 can only access some docker containers on host system

[Born8bit]

I have a VM with GPU passthrough running as a daily system, and all is fine (internet works, can access unRAUD GUI), but when it comes to dockers on the host machine, it's a split thing:

• Some I can reach just fine, like Krusader, Deluge, Prowlarr (all on bridge, running host IP with their port).
• Others, like TinyMM, MKVToolNix show their top bar with a "Server disconnected (code:1006)" red X.

 

Docker log will show this:

The fact that all dockers above have the same network type, the same IP and only different ports and will still not connect the same way doesn't make sense to me. Also I don't know if this is a docker issue or a VM issue, so I went to General.

 

Might be worth mentioning that the VM has it's own IP and all other machines on my network can access all of the dockers without issue.
