Error 400: invalid_request”

I am developing a web app (I am a beginner) and when I run it outside of docker, there are no authorization issues since I have added the redirect to the redirect_uri under Credentials in my Google Cloud Console (GCC).
However, when I run it in docker, I get the “Access blocked: Authorization Error” above.
What is going on here and how do I get around it? Thanks in advance.

I normally resolve this (when running outside of docker) by adding the specified address (in this case: “http://web/market/social-auth/complete/google-oauth2/”) to the redirect_uri under Credentials in my GCC. But when I try to register “http://web/market/social-auth/complete/google-oauth2/” under the redirect_uri in my GCC, I am prevented from doing so and instead I get the message “Invalid Redirect: must end with a public top-level domain (such as .com or .org).
Invalid Redirect: must use a domain that is a valid top private domain .”
