Hello!
I used to have a version of zm_0.6_win and this version worked, I stopped my farm for 6 months, after which I moved to another city. When I tried to use zm_0.6_win, I had a problem with SSL, then I downloaded a new version of v0.6.2, and when I started start.bat my farm is freezes.
What to do

Help me please!
P.S. Windows 10, Nvidia driver 416.81. Cuda. Visual Studio.
You could try to start only 1 GPU (using the -dev option) to make sure there are no power supply issues.
