I hope my post limiting gets removed soon. Its frustrating not being able to post lol.
To answer this question. When you use the 12xxx ports then you will get authorization failed messages if the algorithm you are trying to mine is not the most profitable as configured in your hub.
If you want to mine this algorithm no matter what and just get the most profitable coin from it use the 17xxx ports.
Yes, it worked! Big thanks to JQE!
Probably now I understand the reason for parameter "retrycount = 1" in such cases) It uses for cases where miners pointed in bat file one by other.
Do I understand correctly that when I use 17xxx (17020 in my case) port miner will mine ant ethash crypto according to profitable?
For example, Ehereum, Pirl and so on. Correct?
