Description
I have installed Keycloak 3.4.3. I use a configuration with a load balancer with 2 (local) server instances.
On a Linux machine (CentOS 7) I do not see any errors in the load balancer log. However on Windows (10 and 2016) I see the following errors in the load balancer log:

The application does actually seem to work fine.
