OK, it was one Riser, it is always a riser in the end!!!

this config working now fine!
good that you found a problem

And another Question:
what do you take to remote monitor the miner?
eg: for Claymore and PM you can take Claymore RemoteManager.
maybe one good android app?
THX
miner supports only xmrig-like API with no 3rd part application(at least I don't know any). You can set
--api-port and check on that port statistics in your browser(locally it will look like
http://localhost:6050/ if you use parameter
--api-port 6050), there you will find hashrate per gpu and so on.
