Hello! I start to use firmware on my Antminer z9. But i saw that 4 of them started to mine zec.ss.poolin.com - for dev fee, i guess. But after more than 1 hour they did not change back to my pool. I rebooted them, but the change back to zec.ss.poolin.com. Is this a bug?
Support ID please? Are you running minerstat, by chance? Join the discord and send me a PM to get my attention and we can figure out what is going on here.. to answer your question, no, I expect it is not a bug since these firmwares have been running for months without that type of issue. Let's figure out what is going on in your environment.
Are you mining piratepool by chance? I see problems with piratepool connectivity reasonably often (you can use luxor's arrr pool instead). If your other pools are not configured properly or are not up, cgminer will automatically switch to a working pool.
