Hi th00ber,
I'm having this issue with monitorig.exe 2nd time already. Please check first screenshot.
Miner is reported as offline (I receive a notification mail) on the website but showing hashrate in the miner log window. 2nd screenshot.
Miner is working and hashing properly. 3rd screenshot.

Only one instance of ohm is running, folder structure without spaces. 0% fan as these cards are watercooled.
Reboot or restarting monitorig.exe fixes this, restarting the miner through website interface doesn't.
Maybe you can look into this, thank you.
