Hello Patrike,
It seems I have come across another bug.
It seems that AM is unable to obtain API data from any of the Claymore's software whenever the amount of GPU is equal or above to 10.
To test it, I unplugged GPUs until I was down to 8 and it worked fine.
Then I plugged back in the 9th and it was working fine.
Then I plugged the 10th and once again AM was unable to get stats from Claymore and with it I'm back to the "Interface Offline" message inside Awesome Miner.
Unfortunately, this causes AM to unnecessarily restart the miner every now and then.
I am aware that I can disable the rule restarting the miner but then that will leave the rig down next time a real error happens and a restart is actually needed.
