XF 2.3 XenForo OAuth troubleshooting help needed MediaWiki

[Bryan_D2]

I'm new to XenForo; our whole forum is moving to XenForo from vBulletin in the next few weeks. We have run into a problem with OAuth talking to MediaWiki. So, after a lot of debugging and troubleshooting, I tried a different solution, using WordPress as an OAuth client and XenForo as the OAuth provider. I end up with the same problem. Data is not being sent back to MediaWiki or WordPress. I also tested via curl and Postman; all results were the same.

I'm trying to find a few things.
1) Any logs related to OAuth on XenForo
2) Is there a further configuration outside of the OAuth that I need to enable on the XenForo side?
3) Is there a better way to troubleshoot XenForo Oauth as a provider?


Error message example
Invalid response received from Auth Provider. Contact your administrator for more details.
Response :
{ "message": "Sorry, we're currently unavailable. Please check back later." }

WordPress:
Error
Token Response Received = {

MediaWiki
For MediaWiki I am using the Extensions PluggableAuth and WSOAuth. For WSOAuth I had to build a custom XenForo provider. If I can get this all working, I hope to share it with the world.
Error
The username provided by the OAuth provider is not valid.
Further logging resulting in this
*Token URI during construction: NULL
*Failed to decode token response: Syntax error
*Raw Token Response: false

Thanks in advance for any help or ideas you can share.

Is that all you got in the log for the OAuth login attempt?
With a fresh browser / cleared cookie / incognito tab?

There should be a lot more as shown in https://xenforo.com/community/threa...ing-help-needed-mediawiki.230291/post-1743141

Yup, I've flushed cache, tried in private mode. Also been testing in FireFox, Brave,Chrome and Safari too.

I also flushed caches in MediaWiki too. ( php maintenance/update.php in the MediaWiki root folder. )

I don't see everthing in your post. I see the calls in the code to write to the log but don't see them. I see the below with special edits and redactions. Again thank you for looking.

I've added a bit more logging, maybe this does help.

///At this point the browser flips me back to Xenforo.
///Return to Mediawiki page click on Login with XenForo button again

Hmm ... that's not how it should work:

Thank you again. No I am not seeing that, but seeing you having that is giving me hope. I can share a video if you want.
I see one thing of note and new in the logs "Error: Could not get code from Array"
