We’ve had login with twitter on our site since 2015 and just recently it’s returning:
“The remote server returned an error: (403) Forbidden.” I do not see any supporting codes just this in the response.
I didn’t write the code, which is for asp.net, but the vendor has not reported any other problems. When logging into twitter apps I see a notice about the developer portal being required now. I applied for that and the problem remains. I’ve edited my test app: updated terms/policy urls, etc. verified the keys, and all looks ok. The app is only so we can login with twitter.
I did see the request is pointing to https://api.twitter.com/oauth/request_token and there’s a querystring oauth_version=1.0. Could that be the problem? Neither our test app or production app work - both return this error immediately. I don’t receive the window to accept the app, but see the app in my twitter account already.
Additionally, where can I turn for issues like this if this is the proper place? Thanks.
