Farmer constantly bans remote harvester #57

Closed LeonidShamis closed 3 years ago

LeonidShamis commented 3 years ago

Remote harvester (e.g. 192.168.20.30) successfully connects to the farmer (192.168.20.3) and starts responding to the challenges by looking for the "eligible for farming" plots, but after a short while the farmer closes the connection:

2021-06-21T13:19:06.784 harvester harvester_server : INFO Connection closed: 192.168.20.3, node id: d7409c0adc2e403f7639918ab19c8123504cdcd16092a8beefcf293e0be5d49e 2021-06-21T13:19:06.785 harvester spare.harvester.harvester: INFO peer disconnected {'host': '192.168.20.3', 'port': 9447}

In the farmer log you see the following about the disconnected harvester:

2021-06-21T13:20:49.213 farmer farmer_server : ERROR Exception: , {'host': '192.168.20.30', 'port': 9448}.

The above happens many times - harvester reconnects, works for a short while and then is disconnected from the farmer.

:(

I see that the disconnections always occur after the harvester finds a proof and sends it to the farmer - always after Found 1 proofs. - see below.

What could cause the farmer to disconnect the harvester upon found proof?

@LeonidShamis ,thank you for opening this issue , we will investigate and respond with solution ASAP

msg7086 commented 3 years ago

Banning happens after some validation failed. I wonder if your proof of space was invalid to farmer. Maybe your proof doesn't match your private keys in your farmer?

LeonidShamis commented 3 years ago

I have identified the root cause and resolved the problem. It was due to the wrong GENESIS_CHALLENGE in harvester's config. When Spare blockchain release and update (re-launched), I only updated the farmer to save time. I didn't update the harvester configuration. After updating the harvester config with the correct GENESIS_CHALLENGE, the issue is now resolved. Thank you.
