The merchant you provided in the private comment is a sandbox merchant, not a production merchant, perhaps that is the problem? General information on troubleshooting 401s can be found here - https://docs.clover.com/docs/401-unauthorized.

It sounds frustrating to encounter a 401 Unauthorized error, especially when everything was working fine earlier. A 401 error usually means that authentication has failed, which could be caused by various issues such as expired API keys, incorrect credentials, or permission changes.

Here are a few things you might want to check:

1. Check if your API keys or authentication tokens are still valid and haven’t expired.

2. Double-check that your credentials or keys are correctly configured in your production environment.

3. Verify that the permissions for the API keys have not been altered or restricted.

4. Ensure that you are calling the correct version of the APIs, as versioning could sometimes affect access.
