ScrapBlox does MediaWiki expose their login via OAuth2?

I don't think the base install does but there is a popular extension OAuth to implement an OAuth server.

ScrapBlox in that case if you install that extension you should be able to use sso-oauth2-multiple to connect to it and log in via MediaWiki credentials.

Ah okay. I installed the extension and sso-oauth2-multiple and created the app. filled in the information on MediaWiki and NodeBB but I don't see anywhere to test the OAuth. How can I make it show up on the login/register area?

EDIT: Got it to show up on the login screen but I don't know how to connect it to the MW extension.

EDIT 2: I got the connection mostly to work now it just returns a message failed to obtain access token the nodebb config I got is
Authorization URL
https://{domain.tld}/rest.php/oauth2/authorize
Token URL
https://{domain.tld}/rest.php/oauth2/access_token
Client ID
{the actual id}
Client Secret
{the actual secret}
User Info URL
https://{domain.tld}/rest.php/oauth2/resource/profile
Scope
" "

ScrapBlox any errors from the MediaWiki side? Not sure if there are logs you can check. Similarly, check for logs in the NodeBB side.

julian Kind of new to NodeBB and not entirely sure how to find the output stuff, sorry. Here's debug and oauth logs from MediaWiki though.

Was there any further tips to resolve the "failed to obtain access token" error? I haven't been able to figure it out thanks and apologies for the bumping of a topic.

ScrapBlox hi, sorry about the delay. Sometimes it's hard to think of what to debug next.

Can you screen shot the settings on both sides? Feel free to blur out the client id and secret
