Dear Community!

We have upgraded the macOS to Big Sur and the users fail to connect to the GP gateway due to server cert verification failed

I have read the following article:

But GP was working fine with macOS 10.15 having the same certificates.

+ Did you expierence the same issue with Big Sur?

Thank you!

Please verify that the certificates do not exceed 825 days validity (from not-before until not-after).

I've had this happen for 2 customers 😞
