Hi,

I am installing dcm4chee arclight 5 with the following link, everything seems to work fine until the Keycloak configuration, I have correctly set the Valid Redirect URLs and Root URL as mentionned but when I try to use those redirect url link, I am facing an "Internal Server Error" page for the :8080 link and a blank page with some weird characters for the :8443 link.

If anyone knows how to fix that,

Thank you

paul

What do you see in the server.log? How does your Keycloak client configuration look like ?

My problem is very similar to https://groups.google.com/g/dcm4che/c/lEF4QQ7UOnY/m/hfJren18CQAJ

In the server.log file I've got a WARN line :

2020-06-15 11:24:02,672 WARN [org.keycloak.adapters.KeycloakDeployment] (default task-1) Failed to load URLs from https://localhost:8843/auth/realms/dcm4che/.well-known/openid-configuration: java.net.ConnectException: Connection refused (Connection refused)

and an ERROR one :

2020-06-15 11:04:45,651 ERROR [io.undertow.request] (default task-1) UT005023: Exception handling request to /dcm4chee-arc/ui2: java.lang.NullPointerException

I have tried the solution gunter provided in the above link which consist to modify the firewall parameters with ufw by adding port 8843 but it didn't work, I still got the Internal server error on http://localhost:8080/dcm4chee-arc/ui2

My keycloak client configuration for the archive ui is as follows, nothing really different from the tutorial

Thanks,

AUTH_SERVER_URL can't specify "localhost", because keycloak runs in a different container than the archive.

ok the docker host is different from the server host IP. It should be something like 172.27.....
