Versa SASE VPN Issue

Hello all, was wondering if anyone ever had experienced an issue with registering a device to Versa SASE VPN and gives them an error after attempting to register. The error states unable to communicate to Versa Service. My team and I emailed our vendor but still no resolution.

So far we tried:

Removing my User account from the VPN group through AD

Turning off the windows defender firewall on my laptop

Reinstalling the latest version of VERSA

We think this is a machine issue with my laptop as we tried adding myself to the VPN on a different desktop and I was able to register there.

I am not really sure what else to be looking for as there are not a lot of articles about this particular issue.

I had similar issue connecting to versa gateway from the windows client. The only workaround is to switch wifi to a 4g mobile hotspot (different ISP). I have tried factory resetting and restarting every single device but didn’t help

My only conclusion is my ISP mate NBN could not route the packets to versa gateway.

Managed to solved this via their phone support, they assign me a static ip which become effective after a day and after router power cycle I can connect to Versa SASE.

They mentioned this is a known issue because my ISP (Mate NBN) uses CGNAT for ipv4 which breaks port forwarding. Enabling static ip opts out from CGNAT.
