We’re encountering an issue while updating our OAuth configuration in Spring Boot. Despite providing the new configuration to our provider, we’re still experiencing an error. We reached out to our provider to confirm if there were any mistakes on their end, but they assured us everything is correct and suggested the problem might be with our framework.

Before the changes (specifically updating the redirect URI), everything was functioning correctly in our project. We’re at a loss as to what might be causing this error now. Any insights or suggestions would be greatly appreciated.

We changed the redirect URI and tried both HTTP and HTTPS (providing both options to our provider). We’ve also done some debugging but found nothing useful online. Any assistance would be appreciated.
