What device are you using to connect to the meeting?  If you are using a mobile device then you need to ensure you have the correct app installed.

Android. Adobe Connect - Apps on Google Play

Apple.‎Adobe Connect on the App Store (apple.com)

There is no need to use a VPN to connect to a meeting.

I suspect that there may be some other software installed on your PC, if  that is what you are using, that may be conflicting with your attempts to connect to a meeting. 

Some more details on the set-up of the devices you are using to connect to the meeting would help the community support you better.
