Zoom Security Warning: Untrusted Server Certificate

Environment

Zoom

Issue

The Zoom desktop application creates a pop-up showing a Zoom Security Warning about an Untrusted Server Certificate, asking the user to click "Trust Anyway" or "Do not trust"

Note: this is common on HITS-managed devices

Resolution

This happens because of a proxy. The resolution is to allow zoom.us and *.zoom.us from proxy or SSL inspection: https://support.zoom.us/hc/en-us/articles/201362683-Network-Firewall-or-Proxy-Server-Settings-for-Zoom

  • Michigan Medicine: Please contact the HITS Service Desk (HITS Device Support) for resolution: https://hits.medicine.umich.edu/. This issue is particularly common for MM users because HITS uses a proxy.
  • All others: contact your unit IT and provide this article as instructions
