Unfortunately I am in fact having an SSO issue with discourse now. The return\_sso\_url is always the base discourse page. It should be my application where the process started. That value is in the returned route from discourse to may application along with the nonce. Any chance you have some insight into why this may have stopped working? Basically, the “return\_path” parameter sent to discourse is not being honored and replaced with a discourse url.
