VPN issues via WIFI using Global Protect

I am experiencing some strange issue when accessing sage on a server in the USA, that's only accessible via the GlobalProtect VPN platform. when on LAN using the cable, i can access sage but when on Wi-Fi via FortiAPs (221E) I cannot access sage. the policies for the cable and Wi-Fi are identical. I ones tested this on different network that has more or less the same setup as mine, with 221E fortiaps and 100F Fortigate fw and it works fine with no issues.
