Hello everyone,
my new raspberry pi 4, 8 GB RAM with 2 TB SSD arrived on Thursday. I have installed umbrel without any issues (honestly, it couldn’t be more user-friendly).
While the blockchain was still syncing I started to play around with different apps to get to know the UIs, functions, etc.
Everything was working really well. At some point I read that I can change the alias of my lighning node (http://community.umbrel.com/t/how-to-create-a-lightning-node-alias/1252), so I did and restarted the umbrel via UI as explained in the above guide (step 8), still while the blockchain was syncing.
After the restart the lightning terminal app started to give me errors. After some research I was worried that I must have messed up the lnd.conf, so I overwrote it with a default, as explained here (http://community.umbrel.com/t/default-content-lnd-conf-lightning-configuration-file/5929/2). I restarted the umbrel again (still, the blockchain sync was and isn’t finished).
Unfortunately, the errors are still there, so I think the lnd.conf wasn’t causing the problem. My funds are there (except those in the lightning pool account, because the lightning terminal doesn’t wpork), the wallet works, the channels are up, only a few specific functions don’t work (lightning terminal, in RTL the Swap/Boltz).
Those are the logs I think are relevant for my issue:

After reading though the pinned messages in this forum I realize I shouldn’t have messed with the lnd.conf and restarting the umbrel multiple times while it is still syncing. However, in my defense, it’s quite hard to not play around with new hardware and the cool UI / functions umbrel offers 
From my very limited understanding of the logs I would think the error has nothing to do with the fact that the blockchain is still syncing… Any hints for troubleshooting?
Thank you very much !!
