Can't recover lightning node after update to umbrel OS 1.0

Hi folks
I need some help pls. I searched the forum, but couldn’t find any solution. I have following situation:

3 years ago i installed my umbrel BTC node with lightning. Everything worked fine for about 2 years. After that i had some trouble with my BTC node. It was not running anymore and i couldn’t fix it. So i left my Pi beside. Now, a few weeks ago i started over with a fresh installation of OS 1.0. all good. i was syncing the node for some weeks. after that i wanted to recover my ligthning node with my secret words. but it stucks during the recovery process. i deleted the lightning app and tried again. so it was doing the same. there was this process display, but it was stuck at about 50% and the logfile was showing something like “cannot connect to channel, trying again in 5 seconds” the log was full of it, so i decided to reboot my umbrel. and since then i even cant start the lightning app. it is stuck at the starting screen


i attached the log file too. so maybe someon can help me go bring back my old 0.5 backup files to the new 1.3 version of umbrel?

Update: I managed to ged rid of this splash screen by uninstalling and removing lnd again. i then checked with ssh to be sure, that no files or directory is around and restarted the system and installed lnd again. so now it’s syncing again. cross fingers… i’ll paste an upate here in about 24h again.

No chance… since 2h its stuck at the same point… errormessage in the log:

ightning_lnd_1 | 2024-12-15 15:16:22.130 [ERR] LNWL: Unable to synchronize wallet to chain, trying again in 5s: unable to persist initial sync data: failed to store sync information 00000000000000000007d487eeed8a873704be0aad2a9b9fe8e1198a742c6976: failed to fetch block hash for height 662377: block not found
