When I want to Edit an existing Page or create a New Page I always get following Error:
This page has failed to load
Our team has been notified. Wait a few minutes and try again. If the problem persists, contact Atlassian Support.
Error details: Failed to fetch

My colleagues do not have this problem. And I tried with Google Chrome and MS Edge (Chromium) Browser.
Can you help me or give me an advice what to do.
