Twitter SSO fails at the callback stage

[mz2]

I have entered the twitter login key & secret and authentication callback, but I'm getting one of two possible error messages when attempting to then log in with it.

I get either:
1.

Internal error.
Oops! Looks like something went wrong!
/auth/twitter/callback
This feature is temporarily unavailable

or (without making any configuration changes) …

Internal error.
Oops! Looks like something went wrong!
/auth/twitter/callback
Error processing your OAuth request: Invalid oauth_verifier parameter

I have got all the other major SSO backends working with my instance: Google, Facebook, GitHub all work just fine with their OAuth callbacks.

Do you have a callback url defined?

[mz2]

Yes I do indeed.

[mz2]

It's set to that /auth/twitter/callback

[mz2]

Would the Error processing your OAuth request: Invalid oauth_verifier parameter error message suggest some bug in the authentication implementation as the cause?

Use https://api.twitter.com/oauth/access_token?oauth_verifier=AAAAAAAABBBBBBBBBBCCCCCCC

@samarthsikotara use that where though?
