URL: Username with @

Just do:

 http://my_email%40gmail.com:[email protected]_site.com

I am quite surprised that problem was with username @ and not the password -usually this is where I get reserved characters in url authority or path parts.

To solve general case of special characters: Just open chrome console with F12 then paste encodeURIComponent(str) where str is your password (or username) and then use the encoded result to form url with password.

Hope this saves you some time.

Use %40 in your username instead of the @ symbol for the url encoding. It should pass it properly then.

You need to URL encode the @ as %40.
