Just FYI, I got it working by using the "Get Custom Port" option on MRR. The dev on their side believes your miner is lacking the client.reconnect feature, EWBF was also lacking this early on but has since added it. Glad I have Gminer working,

Please take this into consideration as a lot of people will look to use that flight sheet on HiveOS and it will not work for them unless you add the necessary features.
