ERROR 404 or 502 when trying to log in Instagram after setting my IDs

Hi all,

After setting my Application Client ID and my Application Client Secret and save, I go on clicking Instagram Login and I get the below error or even 502 bad gateway once.

{“code”: 400, “error_type”: “OAuthException”, “error_message”: “Redirect URI does not match registered redirect URI”}

I have tried creating different clients on Instagram and fat chance. This plugin specs seem promising, but I can´t even test it. Any quick advice please?

Thanks
E
