* HTTPS enabled
* BasicAuthentication Enabled

the following errors started showing up in the logs at regular intervals

After some debugging it showed that the error only shows up during the
(seemingly) periodic metrics collection on the leader node. The following stack
is seen in this cases
!image-2019-02-05-11-29-22-569.png!
While trying to debug it a bit if this can be resolved by some additional
settings - for which no solution was found - this method was also called from
another location during collection creation where the authentication seems to
work just fine

So something in this chain must enable the correct authentication settings it
seems.
Appart from periodic error logs generally functionality seems to work but most
likely something related to the cluster metrics is not fully working.
