my bitcoin machine has this problem
The most common fix for this has been to reflash your MicroSD card.
If this doesn’t work feel free to share your debug logs via SSH (by typing ssh umbrel@umbrel.local from a computer on the same local network into a command line) and then using this command:
cd ~/umbrel && sudo ./scripts/debug
You can paste the output to https://pastebin.com/ and share for easy review
