I am trying to apply the requirements to my Palaolto self-generated certificate but I wonder if you can help me on how to apply/configure the following requirement. Can you share more information on how to apply these requirements on the firewall?
TLS server certificates must contain an ExtendedKeyUsage (EKU) extension containing the id-kp-serverAuth OID.
Where you able to generate the certificate with these requirement from the firewall? Or did you have to use for instance OpenSSL or generate a CSR and get the proper cert from a CA?
Have you tried changing the certificate settings on the Mac itself? I changed them to Use System default on my Catalina and it started working. Mind you this was for authentication to global protect but it still may be worth a shot.
I also had this problem on my iPhone (13.5.1) and the Global Protect app. After successfully establishing a connection to my company network most websites would not load and displayed a certificate error due to SSL decryption. Here is the resolution:
1. Verify that your certificate profile is showing up under Settings > General > Profile. You should have been prompted to install this when connecting to GP for the first time.
2. This is the part that I was missing. Settings > General > About > Certificate Trust Settings (scroll to the bottom).
3. "Enable Full Trust" for your GP root certificate.
Once I did this I could browse to any site without certificate issues. Good luck!
So you have to change these settings on the IOS device itself? Were you able to use a self-signed certificate? did you still have to meet the requirements set in this link?
