Hey @Jaguar2026
This points to an issue with the SAML/SSO redirect prior to the VPN establishing. A few things to check:
1. Is the device clock synced with an NTP server?
2. Is the default browser (embedded browser) blocked or disabled by a SIG?
3. Is there any interception of the traffic between device and SSO portal? Could it be blocked in Umbrella/Secure Access/another SIG?
4. Is the SSO portal URL correct?
5. Any chance pop-ups are blocked in the browser?
If you check all of that and it still isn't working, then we will have to go deeper into the problem.
Good luck!

It is working now, it was a problem with the browsers.
