...snip...
Just a data point regarding this: I've noticed several occasions where my Mini has continued to mine for a few hours, but is not mining my pool. I know it has happened with Prohashing multiple times, and I think at least once on Flypool. To the best of my knowledge, its been maybe 5-10 times since 2.1d came out, but I've never spent time on it or looked into any further - I've just restarted and it fixes itself (though that is actually adding some dev mining on restart).
One thought...
There is a new antminer malware that does not infect the miner directly, but instead uses the API to change the mining pools and runs from another infected computer (at least that is what it appears so far). It uses flypool for the mining. I haven't managed to get a copy of the malware yet to figure out exactly what it is doing, however. I confirmed this on another customer's system yesterday and implemented a temporary workaround for that user.
If you happen to be using awesomeminer, you will be able to tell if this is happening to you because all of the pools will disappear except the malware pool.
If you'll catch me on discord, we can troubleshoot it together and see what is going on.
Thank you,
Jason
I have two Z9 Minis running - one with your firmware and one without. This issue only occurs on the one with your firmware. I don't use AwesomeMiner or any other software to monitor, track, etc. It happens when I am mining on prohashing and I could be mistaken, but I thought at least once when I was mining on flypool. I never tried to see where it was actually mining or any other info; I just restarted and moved on. It hasn't been a big enough deal to date for me to worry about - just thought it might be useful info for you if others run into the same issue. Until it happened while I was mining flypool, I assumed it was probably issue on Prohashing's side. And since I'm not 100% sure it did occur mining flypool, I'm still not ruling out that its a Prohashing issue.
