Hello! I think my issues started after updating Core to 2025.7.1. Trying to reach homeassistant.local:8123 renders "ERR_ADDRESS_UNREACHABLE", and replacing homeassistant.local with the actual IP address instead gives me "ERR_CONNECTION_REFUSED". Checking the router gui, I can see that Home Assistant is connected to the network, and pinging both homeassistant.local and the actual IP gives normal output.
When visiting (ip):4357, I get to a screen saying "Supervisor: Disconnected".
I do not have any backups, but also have not installed that much in my Home Assistant setup yet. Thus, I tried to perform a reset according to the instructions (hold the button, connect power, wait until solid lights) – but it did not help either.
Any ideas of what to try next?
