HTTP 401 Response Status after upgrading to 1.8

When accessing the hangfire dashboard there are http requests quietly failing in the background. As far as i've gathered 401 Responses are expected durring negotiation using windows authentication, but in the past they were not treated as "failed".
Our main problem with this is that it shows up as failed in application insights, but it seems to not impact normal use.

The failed responses mostly happen when accessing the dashboard for the first time and when quickly switching between two tabs in the dashboard.
