Farmer not syncing. Err.UNKNOWN_UNSPENT

[duffmanlight]

Updated to v1.2.5 on Ubuntu 20.04.1. It has not synced for a few days. Can't get past peak height of 768994. I have tried:

• System time correct
• Port 8444 is forwarded to Farmer IP
• Turned off upnp in config
• Deleted the peer DB file multiple times, No change. Should I delete the local blockchain db file?
• Rebooted
• Added introducer peer: introducer-or.chia.net

No plotting, just farmer/harvesting.
Thanks in advance for any advice/help on this.

Here is a snippet of the debug.log and this just repeats constantly:

Your db might have been corrupted.
Try deleting the whole db and starting over again

Thank you for the reply jack60612. I deleted the main DB sqlite file and restarted the Chia processes. The log looks better and it is humming along. I'll update again tomorrow.
