I think it's better to uninstall the add on and press F5 when you install again...

[cgtinker]

Do you have VPN running?

Do you have VPN running?

No, I don't have. Why ?

I'd like to know how to fix that too

Do you have VPN running?

Please, help me !

hey, i have recently installed BlendARMocap in my blender and it's working fine, in fact i didn't even installed dependencies because they were already installed, simply install open CV libraries in blender before starting,
First remove the BlendARMocap from your blender
Then follow this video starting from 3:00 to find how https://www.youtube.com/watch?v=O7nNO3FLkLU it shows you how to install openCV
Then add BlendARMocap again
Then let me know the results
