Hi,
My umbrel has been up and running for about 2 months.
I just notice the BTC node is not 100% synchronized is around 3 days behind
I notice it thru the mempool.
I have a very fast internet connection, what could be causing this delay?
I also run a Start9 node and that one is 100 % synced.
I had a similar issue. I cd to this folder on Umbrel ~/umbrel/app-data/bitcoin/data/bitcoin
Then remove settings.json and peers.dat
Then reboot Umbrel.
Bitcoin Node started syncing again.
