Hello Friends, a friendly newbie here.
I have this problem with configuring login with Github on my discourse installation, after providing the necessary API keys required in the **Admin \> Settings \> Login** page in the github setup section.
Clicking on the Github login option redirects to a 404 page and returns the screenshot below.
and this in the URL bar
`https://MYDOMAIN/auth/oauth2_basic/callback?error=redirect_uri_mismatch&error_description=The+redirect_uri+MUST+match+the+registered+callback+URL+for+this+application.&error_uri=https%3A%2F%2Fdeveloper.github.com%2Fapps%2Fmanaging-oauth-apps%2Ftroubleshooting-authorization-request-errors%2F%23redirect-uri-mismatch&state=29b1f640d906a3bf4d92a1fe5846af740eea49adbfbfb65c`

Hi Osioke, thank you for your reply.
I did follow the guide and still couldn’t get it fixed, I eventually found a fix on my own.
Apparently the callback URL from the guide isn’t quite correct, I changed it from `https://mydomain/auth/callback/github` **to** `https://mydomain/auth/github` and everything works well.
Perhaps the guide should be updated for future readers.

Glad you were able to sort it out, interestingly, the guide uses the same URL you shared:
> [@Configure GitHub login for Discourse](https://meta.discourse.org/t/configure-github-login-for-discourse/13745/1):
>
> Be sure to set the Callback URL to use the path `/auth/github/callback` at your site domain. e.g., `https://discuss.example.com/auth/github/callback`
So we are good here.
Seeing as you mentioned you were able to resolve it and you found a fix:

I’ll be closing this off now. Cheers! 🙂
