I got two laptops both with Windows 10.
I'm running them on local connection (in the same network).
What i do? I add a node on both my PCs with as name the other laptop name, and as ip the other laptop's ip
(i get the ipv4 with ipconfig command, example 192.168.1.141).
I press CONNECT button but it doesn't work! After some time it says an error.
To make sure this wasn't my error, i opened a Minecraft Server on my main laptop,
and i connected with no troubles with my second laptop.
Try a ping and see if the it works. If is not working, disable from the windows defender window , Firewall & network protection the private network. You might, as me, downloaded the free version of CR that only works with blender 2.9 and you want to make it work on blender 2.9.x. I am waiting for a reply to see if this is the issue before going for the payed version.
