“Network connectivity was lost. Please wait while the meeting tries to reconnect.”

Similar problem here, but not affecting everyone.  Student was attending a class, tries to connect to the class, and for a second can access the course.  Then gets the Network Connectivity error, and the Attendees and Chat pods blank out.  Any files shared through the Share pod display, audio works, but the student cannot see the shared screen.

Firewall is in place, didn't work. 

Test Solution:  opened the ports for any application, any port to the student's IP address to the website, and the error went away.  But, not safe. 

The client narrowed down the applications needed: 

Enable access to Adobe websites.  Initially it was just *.adobeconnect.com, but adobe.com was added. 

adobe meeting

adobe meeting remote control

After that, it worked.  What's odd is the applications were not marked as "blocked" in the firewall, they just were not allowed to work.  Hopefully that will give someone else guidance as they navigate this issue. 

Special thanks to Brian for working this out for me. 

Dear All,

I had exactly the same problem: the moment I clicked "Desktop sharing" the dialog box informed me of Lost connectivity and after 5 seconds the whole connect desktop turned gray and reset itself.

I was unable to share my desktop!

As it turned out the problem was... that I already had a prior Connect window that was minimized and I was unaware of - did not even know that it was possible!

Once I closed it the Connect returned to normal operation.

Best regards,

I‌f everyone got that message, that's a different story. Would not have been your internet connection in that case. I agree – could have been an outage with Adobe servers. Doesn't happen often but it's has happened to me. Hope you have no more issues!

‌Sorry to hear you had trouble! You left out a lot of detail but I can tell you "network connectivity" is a problem on your end, NOT with Adobe Connect. Your coworkers may be able to still get online but your network had connection issues with Connect.

Do you have a firewall?

Were you hard wired or wireless?

If you were leading the webinar you should be hard wired, in addition to the latest Flash Player and Adobe Connect add-in. Please tell me if you were hard wired.
