Connection Failed GlobalProtect on a Mac

[jayteeville]

I am having an issue logging into the VPN on my Apple devices. I can connect to the VPN via the windows laptop, but I cannot on my Apple laptop. I keep receiving this error message on the Macbook Pro "[Error]: Gateway VPN External Gateway: The network connection is unreachable, or the gateway is unresponsive. Check the network connection and reconnect.". I can successfully access the VPN on windows without any issues, and I am using the same credentials to log in. Has anyone encountered this issue before?

not had this error myself but i assume the login to the portal is OK, or is that failing too and using cached app config for gateway.  what happens when you browse to the portal.??

[jayteeville]

Login to the portal is fine. I can type in the portal address in a web browser and it comes up and I can login on the browser without any issues. I can also access the vpn on the windows without any issues either. The error message populates when I sign onto any Apple products via the vpn software. 

[Mick_Ball]

does the pangps log file show any useful info...  it would be worth checking if GP to portal is ok then fails on gateway only, any certs involved here?  also... i assume you have no gateway restrictions for windows only on firewall gateway settings.

This is in the logs:

do you see a portal login earlier in the logs, are the portal and gateway on same box and using same tls profile.

is it possible to wireshark to see if gateway is responding at all???

not much help.... sorry.

I believed this is related to certificate for the Global protect. Are you using Macbook OS 15.x big sur? If yes probably the GP did not support for this one.

[KennethMcRae]

I had this issue as well and fixed it by adding a Host Name = "DNS" from Subject Alternative Name (SAN) field in the certificate attributes.

@Mick_Ball could be having the idea that you have pushed the CA cert for the globalprotect on the windows devices using GPIO AD directory but maybe you have not done this for MAC using Jamf Pro or other mac managment tool and the MAC does not trust the Globalprotect gateway?

There was also an option for Globalprotect to ignore the portal invalid cert (there is no such option for the gateway) and if enabled even if you have the portal and gateway on the same place using the same cert this could explain the issue.

Also just in case push the system extensions for MAC:

Also if the gateway port is blocked I used this workaround before:

Thanks

I ran into the same problem ,I tested by config certificate Host Name = "DNS" and manually install certificate on iphone and Mac os.
After install certificate found to be able to use Globalprotech as usual.
