I am using subfission/cas "dev-master" branch with Laravel 5.5, PHP 7.0.27 with phpCAS 1.3.5. I have two servers (test and prod) with identical Laravel installations. However, when I go to log in via CAS, one server redirects to the appropriate login screen, while another gives me a white screen with:
CAS Authentication wanted!
You should already have been redirected to the CAS server. Click here to continue. phpCAS 1.3.5 using server https://example.com/cas/ (CAS 2.0)
Clicking on "click here" sends me where I need to go, but I'm very confused as to how this error occurs or even what it means. There doesn't seem to be much documentation on this
