Global Protect on MAC stuck at Portal Prelogin

[schimeha]

Hi !

I am trying to connect to GlobalProtect via Mac - on Windows (same user) everything works fine. 
Pressing the Connect button on Mac shows the Azure Login + 2MFA appears as expected but as soon as I enter the Code
a blank screen appears and Logs are showing the following:

"gp_version":"5.2.9-35","error_stage":"Portal pre-login","error":"Could not connect to the authentication server."
I am trying those connections with Mac and Windows using the same ISP.

Monitor Logs just gives me: Success, Before-Login, Portal-Prelogin.

I'd appreciate any help !!

thx

Hans

in case anybody else is facing the same issue: Certificate validity period.

GPA Logs just displayed: SSL Error - nothing else.

@schimehahow did you resolve the issue, new certificate? I ask because I believe im running into the same issue using a certificate generated from our palo and our mac clients won't trust the certificate.

yes, I had to issue a new certificate which complies to those Apple requirements.
