Hi,
We have problem on Webex connection since version 44.6. Our company is using proxy (PAC) for users' internet connection. Our users were able to use Webex app for meeting with 44.5 or older version. However, once the app was upgraded to 44.6, users could not host or join any meeting with the error below.

On user's workstation, we find that the connections (TCP 5004) are not going through proxy. Instead, the traffic went to the internet directly. As the traffic is blocked by firewall, the Webex app is not working properly.

Once we downgraded the app to 44.5, there is no such connection problem with the same proxy setting. The internet traffic for Webex meeting can go through proxy properly.
We would like to know if the connection mechanism is changed on 44.6. Thanks.
