Hey there,

Since Autocad 2022 is a third-party program, this might be caused by external issues. I found this article regarding a similar issue with Autocad while a VPN connection is on session. Here you go:

I hope this comes in handy for you!

Kind regards,

When Mozilla VPN is on I cannot use Autocad 2022. It seems to block the access to the license on the net.

When you say "on the net" do you mean on your local network, or on the web?

For local network access, see: I can't print wirelessly when Mozilla VPN is on.
