I started the CS50 course recently and keep being notified to link my CS50.me account with my edX account. When I attempt to link the accounts through the link below I am presented with the error that follows. I thought this would be the best place to initially ask this question:

Link Accounts Link

{"error":"redirect_uri_mismatch","error_description":"The redirect URI provided is missing or does not match","error_uri":"#section-3.1.2"}

Thanks for any direction you can provide.

  • Not to worry. The powers that be have been alerted and should respond within a day or two, maybe sooner, but you WILL get a response from an insider. Or maybe a fix will magically appear in .... maybe 10 minutes or so? or maybe later, if the fix doesn't work. Happy coding! ;-)
