Hey there, have you tried restarting yet? The only thing that I’m seeing is that you’re running out of memory due to your 2GB RAM, have you installed any additional apps recently prior to this issue occurring?

@phlippie , do a reflash of SD card with last version, an also do a complete firmware and software update of RaspPi.
To check firmware version use command ‘sudo rpi-eeprom-update’ and follow the instructions to update if needed.
To check software version use command ‘sudo apt update’ , then update with ‘sudo apt full-upgrade’
Restart Umbrel after each updates.
If you already closed the channels and recover funds in Blixt, do not start again your Umbrel with the same seed.
Start from scratch with new instance, new nodeID, all fresh.
Be sure you do not have hardware failures.
The onchain wallet is not shown on the main screen of Blixt. Go to top left drawer and select onchain. There you will see the onchain txs.
Main screen is only for LN.
You can just use Blixt with those funds as a companion of your new Umbrel node.
