Error integrating spotify

Hello. I know this was dealt with thousands of times. I read all the discussions on this topic but could not solve it with any advice.
If someone can help me I appreciate it.

Thank you

Here is the link to accept the integration which tells me INVALID_CLIENT: Invalid redirect URI

I did exactly what the video says and couldn’t fix the error either.
