If you have to use Zscaler, for example to access a corporate network, you may run into issues and need to debug your problem. This article gives a high level overview of how the 2 tools work together
How the tools work together
Charles uses the “External Proxy settings…” tool to forward Charles traffic to an another/external proxy, in this case Zscaler
External Proxy settings
Open External Proxy settings
- Open Proxy -> External Proxy Settings…
- Verify the “Use external proxy server” is enabled
View Zscaler proxy settings
- “Web Proxy HTTP” and “Secure Web Proxy HTTPS” should both be enabled
- These host and port settings (127.0.0.1:32700) are used to forward traffic to Zscaler
- NOTE: your port value may differ from this example.
