Ensure the portal/gateway certificate can be validated using the operating system's certificate store (e.g., Local Machine Certificate Store or Current User Certificate Store in Windows; for Linux, refer to this documentation (https://docs.paloaltonetworks.com/globalprotect/6-2/globalprotect-app-user-guide/globalprotect-app-for-linux/support-for-native-certificate-store-for-prisma-access-and-globalprotect-app)). 2. Remove any certificates associated with portal/gateway validation from the "Trusted Root CA" list on the Portal.  3. Enable portal setting: “Enable Strict Certificate Check” (set FULLCHAINCERTVERIFY to yes).
