Gmail API – Authorized redirect URI

I’m 100% sure there is some sort of firewall miscofiguration.

You have either mod_security, or something else similar activated, that breaks incoming URLs to a server that have &anything=https:// (any URL in a GET param).

To fix that you need to contact your hosting support and say them to disable this security rule. Without this you won’t be able to auth with Google using its API.
