Remote ML not working when Mac in Lockdown Mode

[Qhilm]

• macOS 15.2
• Immich v1.125.3
• Lockdown Mode

It works fine when not in lockdown mode.

Troubleshooting done:

• telnet to Mac's IP on port 3003 does connect: in docker logs I see "invalid HTTP request" or something similar at that moment, hence clearly the traffic reaches the container on the Mac.
• macOS Firewall is configured to allow inbound connection to "ssh"

At the moment, I don't understand what is causing this. Clearly it's the lockdown mode, but the firewall is open, so I don't get it...

If anyone hits that issue and figures this out, I would appreciate a quick reply on this thread.
