Based in the information you posted above with your custom command line, it looks like you are having some error because you didn't remove the brackets. I mean, under this <600> remove this bracket and it is suppose to be like this
--gekko-terminus-detect --gekko-A2X-freq 600 --suggest-diff 32
Also, about your pool, you are using the HTTP protocol, not a stratum. Would you mind using the stratum protocol?
Based on what I know, 2miners has a Stratum protocol; it should work once you configure your miner properly.
Ok, I check the site and here's there stratum URL: stratum+tcp://us-bch.2miners.com:7373
Take note this is a BCH config, and we are currently in the Bitcoin mining section. Moving to the altcoin section might give us more visibility to those who are mining with the same unit and coin.
