TIS2Web SPS Unknown Error Occurred Solution

Problem:
Will you know why I get this when trying to enter tis2web? I am in Mexico.
Using VXdiag vcx nano gm as j2534 passthru.

Solution:
Apparently, it only works in the US  and for other countries you have to have the VPN.

Try installing a North American vpn and access the web if you can
In addition to vpn you need a USA credit card. There are people who rent the account by session or by times.
