I have my Umbrel Bitcoin node in a pc with ubuntu 22.04 with 16gb ram and 1tb ssd. It was working fine since I set it up, about 4 weeks ago, yesterday I noticed that it didn’t syncronized anymore after the block 744,544, it gets to that block and returns again to block 743,897 and it does it again over and over. I rebooted several times, but the problem remains.
I read about the timedatectl, but the time is correctly set and this pc has not been moved or had any power problem.
What worries me more is that I have over 500K sats on my umbrel’s bitcoin/lightning wallet and now I can not access it until the bitcoin node is syncronized and I have been unable to do so since yesterday morning.
Am I missing something?
Thanks
