Zscaler and Charles – Common Problems

I can’t connect to the internet on my laptop

• Open Keychain and check if the Zscaler root cert has been trusted
  • You may get errors on your browser about your connection “not being private”
• If not trusted, update it to “Always Trust”
  • when trusted it will have a blue + symbol (see attached screenshot)

My device give me a private connection error

• If this happens, you will need to download and install your Zscaler root certificate onto the device
• The instructions for installing and trusting a Zscaler root cert is identical to how it works for Charles
  • iOS
  • Android 10 and older
  • Android 11 and newer

My internet traffic has stopped working

• If you have recently restarted your Charles (or your laptop), the External Proxy setting tool may no longer be enabled
