I have recently started playing around with Hive OS. The miner kept failing to connect with the default setting in Hive OS portal. Sometimes it would say things like “Connection Remotely Closed by usw-eth.hiveon.net” and after some tinkering, it started giving some generic errors like “Operation canceled.”

Some errors that I was seeing..

After some troubleshooting, I finally figured out what the issue was. In the miner config, there is a Pool server URL. This needs to be setup correctly. I was using the Hiveon pool and for it, since I selected “SSL Urls,” I had to also change the Pool server URL to stratum1+ssl://%URL_HOST%.

In the miner config, this URL must be set according to the Pool config.
