You will see an error message if the system detects activity from several IP-addresses during a single login session.
This may happen if your Internet provider uses different canals for transferring data (satellite connection) or has implemented bandwith throttling for its users.
Such login attempts are being blocked for security purposes.
If you keep seeing error messages during login attempts, you may disable IP-address verification in your account settings.
To disable it, please visit your Passport account page and change the IP-address verification settings in the «Additional security measures» tab.
You can reenable this feature at any time.
