Network Firewall or Web Security Gateway
If your app stays in a "connecting" mode or timed out due to "Network error, please try again" or "Can't connect to our service, please check your network connection and try again" - it could be related to your network connection, network firewall settings or web security gateway settings.
Note: Check your network connection by opening a browser and ensure that you can access https://zoom.us
Note: We recommend whitelisting zoom.us and *.zoom.us from web security gateway's SSL inspection
To configure your network firewall, please see the following table:
