Endpoint Error- FW/AV

Hello ,
My users are getting Endpoint Error- FW/AV
What could be the issue?

Root cause could be your local firewall or antivirus not allowing proper communication.

Refer to those articles:
https://help.zscaler.com/z-app/zscaler-app-processes-whitelist

and ensure needed destination IP ranges are granted on your local firewall.

How to find the destination IP ranges

Hi Kasun,

If you granted the listed processes to communicate and also ensure your whitelisted IP range 100.64.0.0/16 then you can refer to additional docmentation available here:
