Mac taking very long time connecting to global protect gateway and sometime they gets dropped

[Nvempati]

Mac taking very long time connecting to global protect gateway. We are using the clinet version 4.1.11-9.
Pre-log on always on VPN.  It tries and tries until it connects. Sometimes it drops the VPN and tries to reconnect. All I see suspicious  from the logs are below. Can anyone please assist with this ?

@Nvempati,

SO it's failing portal auth. Is this the only Mac in your environment or do you have other Macs working okay? If you search your system logs with the query ( subtype eq global-protect ) you should see the auth failure reason that the firewall is giving.

Thank you very much for the reply. But the system logs doesn't have anything in it

@Nvempati,

That's really odd. The client logs are pointing towards some sort of portal issue, but if your logs aren't supporting that it points more towards a client issue instead. Do you have other macOS devices that are connecting without issue, or is this your only macOS endpoint?

This is intermittent. I could say sometime or other its happening on some other mac's
We were not able to find this issue when its happening . The only thing we get is logs
