Error 407 and wrong login or password

What you need

The login and password from the order. Authentication is by login and password; the issued format is host:port:login:password.

Quick check

1. Copy LOGIN and PASSWORD from the order again. Do not type them by hand: it is easy to mix up similar characters.
2. Remove spaces and line breaks at the start and end.
3. Make sure you enter the login in the login field and the password in the password field, not HOST or PORT.
4. Check that the details belong to this order and proxy, not another one.
5. If the program saved an old password, delete the saved connection and add it again.
6. If the password contains special characters and you paste the details into an address like LOGIN:PASSWORD@HOST:PORT, it is better to enter them in the program's separate fields.
7. Make sure the order is active.

What it means

1. 407 Proxy Authentication Required: the proxy requires authentication, and the program did not send the details or they are wrong.
2. 401 Unauthorized: this is a response from the website itself, not the proxy. The problem is access to the site, not the proxy.
3. The login window keeps coming back: the details were not accepted, and entering them again will not help until they are corrected.

When to contact support

If you copied the details again and the error remains, contact support.
