Enable 3-legged OAuth

[mvented]

Hello, I’m a newbie on Twitter dev, and not a dev myself.
I’m trying to follow this guide to setup a new app for a crowdfunding marketing tool:

However, the guide is outdated, and can’t succeed in setting it up.
I try my best, activate the oAuth 1, and reach this stage:

By clicking on Authorize, we get to a notice: “redirecting you back to the application. this may take a few moments”, that however keeps loading for a long while, than brings to a timeout error:
cURL error 7: Failed to connect to 66.249.134.126 port 3128: Connection timed out (see curl.haxx.se/libcurl/c/libcurl-errors.html)

I truly have no idea on how to fix that.
Any idea?
Thank you so much to anyone willing to help
Max

This usually means your callback URL is wrong, or is unreachable. You might want to edit or make sure your server is up and running.

Otherwise, the Consumer Key and Secret, is called the API key and Secret, on your dashboard: https://developer.twitter.com/en/portal/projects-and-apps and so are the Access Token and Secret, which you can copy and specify directly, instead of going through the Login with Twitter flow.

Thank you so much. I think the problem is with the callback server actually, as you say.
