Cisco Anyconnect VPN issue

VPN
1

I am attempting to connect to the Anyconnect VPN on a work device, but have been getting an error stating “Could not connect to server. Please verify Internet connectivity and server address” when I try to connect to the VPN via wifi. My network is connected and shows that I have internet access, but I cannot connect to the VPN. All of my other devices are working properly and connecting to the internet. I also tried to use a mobile hotspot and could connect to the VPN just fine. I have tried rebooting the device and router. The router is new and is the Netgear Nighthawk AX2700.

Does anyone know what could be causing the modem connectivity issue with the VPN? Could it be something with Ipv6 vs ipv4?

​

SOLUTION: I just had to disable IPSEC ALG in the settings.

Sounds like a policy in your network or your ISP is blocking you from establishing the VPN if it works over a different network. Check the policies on your router to make sure the security settings are not blocking VPN. What ISP do you use?

Could possibly be a dns issue. When on your home network, see if you can lookup the address your Anyconnect client is trying to connect to. Compare the lookup with what you get while on your mobile hotspot and confirm they’re the same.

How did you disable IPSEC ALG in the settings ?

Did you ever figure this out? I am currently facing the same or similar issue while working with the anyconnect vpn
