Unable to Start or Join a Meeting, The Meeting Client Hangs at 10%, 86% or 99%

Unable to start or join a meeting, the meeting client hangs at 10%, 86% or 99%.

Meeting hangs at 10%, 86% or 99% while trying to start or join a meeting.

The join process may hang if the meeting installer is not able to run properly. 

Potential Causes:

  • SSL inspection may be enabled on your proxy or firewall settings
  • Anti-virus programs may be blocking the installation
  • ICAP Scanning is enabled

To fix the issue, try the following:

Create an exception rule for *.webex.com and atmgr.exe

For help with network configuration for Webex, see:  WBX264 - How Do I Allow Webex Meetings Traffic on My Network?

Disable ICAP scanning and SSL Inspection

Webex meetings do not load when ICAP and SSL interception are enabled on a ProxySG appliance. The meeting client connection can not be intercepted due to the streaming nature of service.

Disable ICAP scanning for the Webex domain name and add the following to a CPL layer in your VPM or in your Local Policy:
<cache>
url.domain=//Webex.com/ response.icap_service(no)

To disable ICAP and SSL interception on a ProxySG appliance, see the following Symantec article: https://support.symantec.com/en_US/article.TECH246275.html
