If you’ve created and linked your own Google Cloud Console project to Make using your own project’s Client ID and Client Secret values, you should not be seeing that error.
Once you’ve set these up, you can use/reuse the same Make connection for all the supported Google apps & modules on Make - you’ll only have to enable the respective APIs for your custom app in Google Cloud.
I’ve tried all of those redirect URLS collectively and individually to establish the connection. The make.com url’s don’t establish a connection and emit an immediate error. All of the integromat URL’s give the same error - as to be expected.
The problem persists, and I find it odd that I’m the only one experiencing it since the instructions are outdated - I’ve had the problem for two weeks and just backburnered it until now thinking either the instructions or issues would resolve.
Figured it out. The Web app needs way more configuration than what is shows in the instructions. The redirect URL is maybe part of the problem, but the instructions in general are insufficient.
