Summary
Since the transition to MV3, browser monitors (clickpaths and single-URL monitors) might fail with a 401 status code on challenge-response pages where it was previously possible to bypass such challenges.
Resolution
-
For such pages, you first need to set up HTTP authentication in the browser monitor settings.
- In browser clickpaths, Enable HTTP authentication and provide credentials in the Navigate event.
- In single-URL browser monitors, select Advanced setup in edit mode and Enable global login authentication. Then select HTTP authentication and provide credentials.

-
Additionally, you might need to ignore the 401 status code in browser monitor settings in edit mode. Select Advanced setup and turn on Ignore specific status codes.
Previously, adding credentials, even dummy ones, into the HTTP authentication fields allowed 401 challenges to be bypassed. However, updates to the Dynatrace Synthetic Recorder extension, required by Chrome, have caused this solution to be deprecated starting with Dynatrace version 1.257.
