My Umbrel node running on a Raspberry Pi 4 (8 GB/1TB SSD) no longer fully syncs. Instead, it gets to within a few blocks of the highest block and then reverts back to a much older block (2-3 days prior) and tries to sync again. It’s been doing this in an endless loop for over two weeks now. The problem began after updating to 0.4.4 and I had hoped 0.4.5 would fix the issue, but it has not.
Do I need to fully restore the node from the backup seed? I have over 20 Lightning channels (backed up) that are currently down. What’s the best way to fix this?
