IDEA Calculation ConnectionError

For an app in our production environment we are using an IDEA Statica calculation, however at the moment we are experiencing an issue. When we start a calculation an ConnectionError is raised which it didn’t do before. The app has not been updated so we don’t know what is going wrong. The traceback is the following:

Traceback (most recent call last):
  File "viktor/core.pyx", line 558, in viktor.core._ResponseStream._create_iterator

viktor._vendor.requests.exceptions.HTTPError: 403 Client Error: Forbidden for url: https://api-bam.viktor.ai/workspaces/46/files/3359/download/

The above exception was the direct cause of the following exception:
