[umbrelOS 1.2 beta] nextcloud runs but i cannot access it

I installed umbrelOS 1.2 beta on my raspberry pi on a usb drive. Everything works fine and multiple apps i tried work fine (tailscale, bitcoin node, …).

However i always get a connection refused on the nextcloud url running on port 8081 even though everything looks fine and the firewall rules are in place.

Any clue what the issue could be here?

Ok i reinstalled, and now even the Bitcoin Node is not working anymore, seems like it is downloading containers with the wrong architecture:

bitcoin_app_proxy_1    | exec /usr/local/bin/docker-entrypoint.sh: exec format error
bitcoin_app_proxy_1    | exec /usr/local/bin/docker-entrypoint.sh: exec format error
bitcoin_app_proxy_1    | exec /usr/local/bin/docker-entrypoint.sh: exec format error
bitcoin_app_proxy_1    | exec /usr/local/bin/docker-entrypoint.sh: exec format error
bitcoin_app_proxy_1    | exec /usr/local/bin/docker-entrypoint.sh: exec format error

After another reinstall, everything seems to work now. But really weird that this exec errors showed up.
