Does running a VPN block my video to a zoom meeting?

[RedMagnolia]

Hi,

Need some help here. Normally I Zoom from my phone but I'm in a class that is running on Zoom. Today in the intro to the class, audio worked but my video was either black with my name or a general prohibition sign. Zoom is showing my web cam but after the meeting and trying to figure things out the only thing that came to mind was the fact that I run a VPN. Could that be the issue? Is there anyway to test this out before my class on Monday?

I have to say as a former IT Systems Engineer I'm really embarrassed that I can't figure this out.

Thanks for your help.
