Open WebUI v0.6.0 Crashes After Initialization on Umbrel - Port 8080 Not Accessible

Hi Umbrel team,
I'm running Open WebUI v0.6.0 on Umbrel, and it consistently crashes after initialization. The logs show it loading WEBUI_SECRET_KEY, SQLite database, and environment variables, ending with a CORS warning (WARNING: CORS_ALLOW_ORIGIN IS SET TO '*'), but then it restarts in a loop without starting the web server. Port 8080 is not open (verified with nc -l -p 8080), and the proxy (open-webui_app_proxy_1) fails with "The address 'open-webui_web_1' cannot be found", resulting in Connection reset by peer when accessing http://localhost:2876.
What I’ve tried: Restarted, reinstalled Open WebUI, updated Umbrel, stopped all other apps except Ollama (which works fine at 10.21.0.4:11434).

Status: Container shows Up X seconds (health: starting) then likely restarts (no shell access to debug further).

Logs: Attached below from sudo docker logs open-webui_web_1.

Any ideas on what’s causing this or how to fix it? Thanks!

Start with the reported sudo docker logs open-webui_web_1 output and the Open WebUI v0.6.0 container and proxy status. Reproduce the restart loop while checking port 8080 and the open-webui_app_proxy_1 connection; done means identifying the startup failure and restoring a reachable web server through the proxy.
