Class: Users get a “Connecting” or “Connection Failed” Error When Joining any Class

Last updated: November 23, 2021.

Platform: Mac, Windows, iOS, Android

Version: All

Issue: When users try to join a class they stay at a “Connecting” or receive a “Connection Failed” error indefinitely and the user is unable to join any class.

Workaround: To correct the issue:

A. Disable the option to “Require users to update the client” in Zoom under the Admin Options.


B. Set the minimum client version to what Class SDK version is in use, currently 5.7.6.

Notes: This issue can occur if the organization has the Zoom Admin Option to “Require users to update the client” enabled. Since the Zoom SDK is slightly behind what the Zoom client app version is, Class can’t connect because Class doesn’t meet the minimum client version configured in Zoom.
