ZOOM RECOMMENDATIONS FOR CONNECTIONS OVER PROXY: https://support.zoom.us/hc/en-us/articles/201362683-Network-Firewall-or-Proxy-Server-Settings-for-Zoom
We support https/SSL proxy server via port 443 for Zoom traffic.
Note: This does not apply to the Zoom Phone service.
Zoom automatically detects your proxy settings. In some instances, you may be prompted to enter the proxy username/password.
Note: We recommend allowing zoom.us and *.zoom.us from proxy or SSL inspection.
