Farmer synchronization has frozen on block 433,631 and will not make progress.
After some time the farmer will stop attempting to sync and move on to plotting. There is no problem with plotting and the farmer shows that I have plotted 93.13 GB but it is only caught up to block 433,631.
The error hasn’t been resolved by updating versions of Pulsar or by re-initializing the farmer and increasing the plot size from 50 → 100 GB.
After replacing the HDD with an SSD, there was no difference. Even when I wiped the farm, it would not connect.
But, I was able to resume syncing by disabling the Microsoft Defender Firewall. I did not have that problem on another farm running Windows, so I’m not sure how that became relevant midway through syncing, or how it was possible for plotting to continue.
