Google My Business Error [404] Method not found

Hey Guys,

I have built an automation for answering my Google Reviews with the Google My Business API. It was a bit of a pain in the ass to get the API set up but in the end everything was running perfectly fine for a couple weeks. Since a few days i always encounter the following error:

The operation failed with an error. [404] Method not found.

I dont really understand the problem, because everything was already running. From time to time the Google Module lost its verification/connection and i needed to set up a new Client password but then it worked again for a couple days.

Has anyone an idea what it could be?
