Error 500 when authenticating via API and using redirect_uri

https://www.dropbox.com/oauth2/authorize?response_type=code&client_id=6g7ilx7mk0okwo1&redirect_uri=https://pidgn.io/auth.php

It's odd, if it's a first time user, it'll work just fine. But re-authenticatingcauses the 500 error. Maybe it's due to the fact that the app is already authed and setup.

If that's the case, how do I re-auth a user for my app?

An additional piece of information.

I created another temp app and connected my webapp to it. And it works flawlessly.

One thing I did do that I forgot to mention, is rename the App that's currently not working. I renamed the folder it creates in the user's Dropbox. Maybe this will help find the root cause on your end.

Thanks,

I am getting this error - it's 8/21/2019 - what's the issue, please?
