Github authentication redirect error

[iamtunde ('Tunde Yusuf)]

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

Hello Tunde, nice to see you here

Did you follow this guide to setup your GitHub login?

Configuring GitHub login for Discourse

Go to https://github.com/settings/developers, then look for OAuth Apps in the left menu. Select New OAuth App. Fill in the required fields. [image] 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 (Optional) Upload a logo that users will see when signing into GitHub from your site. After creating your application, you should see the Client ID and Client Secret. Enter those in the Discourse…

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:

@codinghorror

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:

@iamtunde

I eventually found a fix on my own.

I’ll be closing this off now. Cheers!
