## Problem(s)

"I get an error message from Zoom that says 'This site can’t be reached' or a message that mentions a DNS or connection error."

"I received a 'You are unable to connect to Zoom. Please check your network connection and try again.' message."

## Solution(s)

<details>
<summary>There may be an issue with how Zoom tries to sign you in...</summary>

If you enter your full email as prompted, Zoom may direct you to "[calpoly.edu.zoom.us](http://calpoly.edu.zoom.us)" instead of "[http://calpoly.zoom.us](http://calpoly.zoom.us) ". 

To fix this issue, click **I know the company domain** and enter "calpoly".

<summary>Toggle your GlobalProtect VPN connection.</summary>

This occurs most prominently with Macs connected to GlobalProtect VPN and Zoom. You can reconnect to Zoom by disconnecting and [reconnecting to VPN](https://calpoly.atlassian.net/wiki/spaces/CPKB/pages/2425144).
