When Logging into OpenShift Console, if you do it twice (by accident), you often end up with a white browser screen. This typically happens if many Browser tabs are open and are used across several sessions. In the Browser URL you see the issue: 

https://console-openshift-console.apps.ocp5.stormshift.coe.muc.redhat.com/auth/error?error=invalid_state&error_type=auth

As soon as you delete "/auth/error?error=invalid_state&error_type=auth" from the URL you end up on the OpenShift Console starting page.

    1. Open two Browser Windows and in both select i.e. your htpasswd or kubeadmin login provider, so that in both windows you can enter username and password.  
    2. Enter username and password in the first browser window, which will result in a successful login
    3. Now do the same in the second Browser Tab and the described issue occurs: https://console-openshift-console.apps.ocp5.stormshift.coe.muc.redhat.com/auth/error?error=invalid_state&error_type=auth with a white browser screen

    Seems to happen sometimes also in other situation, but the one described was reproducible
