Symptoms

This article explains why the use of the at sign (@) as part of a password for the http proxy access is problematic.

Diagnosis

The URI scheme uses the at sign (@) to separate user information, i.e. username and password, from the hostname part. Therefore, it is not recommended that the at sign be used in http proxy passwords.

Solution

To solve the issue, apply URI encoding to the at sign in the password.

An example of a URI encoded password:

[email protected]
-->
p%40ssword
