Ok so, ive a got bit random mix of computers, given they are all the same dell workstations with RTX 2070.. some are running centOS , some are Windows and some others are Ubuntu.
and there are a few leneovo laptos also.
I even have a few random macs (mac pro, iMac and a few macbooks) around and I tried to get any of those connected to each other, the best I get was with a ubuntu server and a windows client, it would show as connected and synced but the render didnt start.
They are all connected to the same physical switch, there is nothing blocking anything, I even tried with disabling the firewalls, and even direct connected a few machines using a "dumb" switch and manuall assigned IPs, hell i even tried running a DHCP/DNS server on it but that also didnt help.
I have even tried to get my 2 laptops at home to "link" (windows/centOS alienware and debian thinkpad) .
I also tried to run blender as root and still, nothing, dead.
and of course I tried with cloud connect thing, but that just resulted in more of nothing.
I tried 2.79b and 2.8 final, but I cant get anything to work at all, am I overlooking something totally obvious here? it just dies at failed to connect..
