I have recently upgraded my mac from catalina to big sur 11.2.1. My earlier global protect client was working fine with catalina but after mac upgrade I upgraded global protect client to version 5.2.4. After doing this I'm getting the error of Connection failed Could not connect to the global protect gateway after entering my username and password. On web I'm able to login into portal but on client I get the above error. Is some additional setting required in mac big sur to connect to the portal? Kindly help as I'm stuck since few days I can't understand this issue.
Kindly take a look here:
"TLS server certificates must have a validity period of 825 days or fewer (as expressed in the NotBefore and NotAfter fields of the certificate)"
and check if you use a certificate that is issued to more than 825 days - if so, generate a new one and test.
Also use GP version 5.2.6 - there is a possibly related issue fixed in it.
