Fullnode Bitbox02 "Response timeout"

Good day,

I get the error “Response timeout” when trying to connect my own full node in the bitbox app. It has always worked without problems so far. I’ve tried everything and searched the web. Can’t find a solution. Config: Raspberry Pi 4B with Umbrel OS Bitbox02 Bitcoin only
All latest updates
Connection not via Tor, only locally with umbrel.local:50001, as I said, has always worked so far. Accessing the Umbrel over the network is also no problem. Would be grateful for ideas.



Maybe the reason is Electrs?
It says " Waiting for Bitcoin Node to finish syncing…"
Bitcoin Node ist synced 100%
