Network Firewall or Proxy Server Settings for Zoom Follow

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:
