I am working on allowing users to log in to my website using Yahoo. I have intermittent problems with Yahoo Oauth2. I will generate the url to request the authorization code and it will get to the Yahoo login sometimes. Other times I will get the window with "Uh oh Looks like something went wrong. Please try again later. Developers: Please specify a valid request and submit again." and the url will have error=invalid_request&error_description=invalid+redirect+uri
My request url is configured on the yahoo console. Also I am using https on a server connected to the internet (not a local machine)
My request authorization was created using the one in https://developer.yahoo.com/sign-in-with-yahoo I have https://api.login.yahoo.com/oauth2/request_auth? client_id={MY CLIENT D} &scope=openid &nonce=4c29ac770b9b1d795b &prompt=consent &response_type=code &redirect_uri=https%3A%2F%2F{MY WEB SITE}%2Fcallback_yahoo.php
I am out of ideas at this point. Thank you
