Hi…I ran keycloak with postgres behind nginx reverse proxy. When I created users, it is Okay. But when I tried to delete the users and set the users password, " An internal server error occured" and “User cannot be deleted” appears on the keycloak web page. Please give me advice on how to solve it out. Thanks to All.
Hi, did you find a solution for this issue?
I have temporary solution.
My configuration is 3 keycloak instances + 1 for database and 1 for nginx. During troubleshooting I have found that by running only with 2 keycloak instances everything works. If I am running with clusters 1 & 3 or 1 & 2 or 2 & 3, everything works. But when the 3rd instance joins the cluster I get the same issue.
Did you find solution? I got same issue.
My configuration is 3 keycloak servers + postgresql + nginx.
I found temporary solution by turning off one keycloak server. Running now with 2 keycloak servers + postgresql + nginx. Keycloak version is 19.0.0.
My solution for this was to add in keycloak.conf:
cache-config-file=cache-ispn.xml
And change number of owners to number that is equal to number of keycloak instances, in my case 3.
