Keycloak token is not being refreshed when it expires

Interface just displays never-ending loading bar at the top when this happens.

I think this is related to issues that we already had. Keycloak uses two tokens - one short term token that is given to the GUI client and a token with a longer lifetime that exists inside Keycloak. If the second token times out, it is possible that Keycloak can not refresh it. We decided to increase the token life time for this token but maybe we missed to do this for the"default" keycloak DB as well? If this is the case, solving this problem could be combined with #162
