Unable to Start or Join a Meeting, The Meeting Client Hangs at 10%, 86% or 99%
Feedback?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 review this Symantec article.
