Too many redirects error after logout timer

[preems1]

I have a session timeout implemented through Redmine's settings. When that timer ends, I get a "too many redirects" error on page refresh.
I used Keycloak

Hi, I also experienced this problem and I have created a PR (#55), for this problem, it looks like it working fine so far in our place, if someone can check it that will be good.
