Harvester plots not being checked

[juggernog20]

My harvester is showing as connected to the full node and there is data transfer happening between the two but in my logs I am getting the following error and it shows that only the full node plots are being checked:

2021-05-28T08:47:06.795 harvester harvester_server : ERROR Exception: <class 'concurrent.futures._base.CancelledError'>, closing connection None. Traceback (most recent call last):
File "chia\server\server.py", line 536, in api_call
File "asyncio\tasks.py", line 435, in wait_for
concurrent.futures._base.CancelledError

For clarity: The full node correctly shows and updates the number of plots on the harvester, they just aren't being checked by the farmer.
