Hey, so I'm mining SIGT on supernova with 6 x 1080Ti's and often I get stratum connection failed, my 2 x 1080ti rig has none of these problems so don't think it's a connection issue.

my rig is 4gb ram, 3930 cpu, asus prime-A , USB powered risers, GPU's 80% TDP, + 60 core, memory - 502 , 70c

sometimes the chrome remote desktop connection takes ages to connect or doesn't connect at all , could be a faulty riser/card?
