Social login - Google SSO Error 400

Hi,
I’m a new Nextcloud user and I’m trying to start a Social login app that uses google account authorization.
I followed the instructions:

github.com

zorn-v/nextcloud-social-login/blob/master/docs/sso/google.md

# How to Setup Google SSO

These instructions assume "https://example.com/" is the base URL for your NextCloud. Adjust according to your setup.

1. Install the app (see README.md)
2. Setup a Google Authorized Domain
    1. Go to Google Webmaster Tools: https://www.google.com/webmasters/tools/
    2. Click "Add Property" and enter the full domain that your NextCloud will be accessible at, e.g. example.com
    3. Optionally verify your site.
        1. Verify your site ownership via the various methods shown here https://support.google.com/webmasters/answer/9008080?visit_id=637032436952938937-2175615075&rd=1
        2. Wait a while.
        3. Confirm that in Google Webmaster Tools you see the property (i.e. domain) you've entered is verified
3. Setup a Google app
    1. Go to https://console.developers.google.com/
    2. Click the list of projects at the top then "New project"
    3. Enter whatever project name you want, no need to specify an org; click "Create"
    4. Click "Create credentials" then click "OAuth client ID"
    5. Click "Configure consent screen"
    6. Enter values:
        * Application name: something relevant

my domain is nx.mama.com
in Credentials I have set up
Authorized JavaScript origins: https://nx.mama.com
Authorized redirect URIs: https://nx.mama.com/index.php/apps/sociallogin/oauth/google

In Nextcloud social login I then put “client ID” and “client secret” in the google field.
Next, in /var/snap/nextcloud/31908/nextcloud/config/config.php
I set

overwrite.cli.url' => 'https://nx.mama.com'

and restarted “snap.nextcloud.apache.service”

When I try to log in via the google button, it redirects me to a page with a message:

Access blocked: This app’s request is invalid

email
You can’t sign in because this app sent an invalid request. You can try again later, or contact the developer about this issue. Learn more about this error
If you are a developer of this app, see error details.
Error 400: redirect_uri_mismatch

I tried to find a solution somewhere but failed. Can anyone point me in the right direction and tell me what this might be?

Google Integration for migration works like a charm.

Thanks a lot
