Umbrel Dashboard UI Won't Load - But Spectre Desktop Will Load

My Umbrel Dashboard / Login page won’t load “Pulling new containers…”

However, Spectre Desktop will work when going straight to that URL.

Issue started after updating to Umbrel 0.5.3 from 0.5.1, so re-flashed SD Card to 0.5.1

Umbrel 0.5.1
