I am not able to configure or run the new keycloak 20.0.2?

HI Lakshmiphani , In keycloak.conf file you give path to access certificates configured .
ensure you give fully qualified path name , it works like charm, example : {kc.home }/path of certificate you may be missing “/”.

@LakshmiPhani7680 did you try the “hostname-admin” argument ?
Bacause the admin console is disabled by default.

Example :
kc.sh --verbose start --db=postgres --db-username=keycloak --db-password=
–db-url=‘jdbc:postgresql://10.133.5.1/keycloak’ --db-schema=public --proxy=edge --hostname=$sso_hostname --hostname-admin=$sso_hostname
