GP issue with IOS device

L3 Networker

We are facing issue with connectivity using GP in I Phone devices.

We are getting the below error.

gateway apple T the network connection is unreachable or the gateway is responsive check the network connection and reconnect

We tried installing new set of certificate with pkcs format on iPhone yet it is not working.

We checked the Monitor log where the portal login was successful but we got the above error.

What could be the issue with that. Current IOS is 14 and the GP is under 5.2.

This was working fine two days back after the certificate got expired we renewed the certificate but not able to connect to internal network.

When you say you aren't able to connect to the internal network, are you saying that you can't connect to the VPN on these devices at all or that you aren't able to connect while on your LAN? Have you verified that the new certificate is actually considered valid by the device? 

Hi, We have checked the certificate under iphone settings where the profile is verified.

We are able to se the successful login message in the monitor global protect tab but we are getting below error after we provide our username and password.


Please find the details below.

@Vijaygvasan make sure also that the certificate is fully trusted on IOS devices, under General>About> Certificate Trust settings.

The Same certificate is working as expected in both Android device and windows machine. But when it comes to IPhone it is not working. Also above screenshot shows that the certificate is verified

@Vijaygvasan you will need to activat this also

Will this be inside more details tab?? Or can you guide me where i could find the above mentioned certificate trust setting

under Settings>General>About> Certificate Trust settings.
