[BUG] Connected to multiple peers but not syncing

Describe the bug My farmer (farmer, full node, harvester, wallet, daemon) running on Ubuntu 20.04.2 (chia version 1.1.6.dev0) stopped syncing overnight/this morning, and now won’t sync even though I’m connected to multiple peers. Has been stuck on block 278867 since syncing/farming stopped.

To Reproduce Started my farmer with chia start farmer. Have tried a chia stop all -d and starting up again. Port 8444 is open.

Expected behavior Should sync up when connected.

I am also having the same issue.

I have tried a few things,

• deleting blockchain database and peer database
• deleting just the block chain database and restoring from a point when i wasn’t having issues.
• deleting the peer database
• rolling back to version 1.1.4
• adding official introducers as peers

One thing i’ve noticed, is that whilst syncing after restart or these deletions, is that i’m connected to multiple peers that are up to date, using chiastatus.com as my point of reference. But some time after reaching sync it starts to lag behind, i notice a few ‘unfinished’ header hash in the blocks ‘pane’ on the ‘full node’ window. Sometimes it recovers, but other times it ends up falling a few minutes behind.

I have port forward enabled, and had no issues previously. Was running on 1.1.4 when i started, about 10 days ago, and updated to 1.1.5 maybe 2 days ago.
