How do you solve this situation with AX-1800?

AX-1800 cannot log in to the surfshark account in wireguard. Click to save the login prompt "Acquisition of third-party provider token invalid 20001211" How can you solve this situation?

Network problems are more likely, cannot be reachable to the surfshark.

Can the phone/laptop APP get the surfshark profile on this network?

The mobile app can be used to log in, but the prerequisite is that you must log in in a VPN environment. After I tried many times, I could log in to the router, but I could not connect successfully when I chose to load location information. I use it in China

Probably it limited by the network environment of the local country, and the IP of the VPN provider may be blocked, casing it cannot be updated the profiles.
