Bitcoind node has stopped. – Bitcoin Stack Exchange

My node stopped at version 26 about a week ago. I updated to version 27 and re-downloaded the entire chain. My node is stuck on ant block 840959. I tried rebooting the entire server. I don’t want to re-index everything. It will take a whole week again. How can I solve this problem?

I don’t know if this is related, but I also run an lnd node. OS: Ububtu 22.04

hardware:

Intel Core i7-2600
HDD2x HDD SATA 3,0 TB
RAM4x RAM 4096 MB DDR3
