2. Java 11

Note:-

When i am using development mode everything works fine.

 ./kc.sh start-dev

Answer 1

When Keycloak is running in Production mode over HTTPS, the aforementioned issue may arise if you are using IPADDRESS in place of HOSTNAME to access Keycloak UI. So one solution is use below command

./kc.sh start --http-enabled true --hostname <HOSTNAME>

and then access Keycloak UI with this url

https://<HOSTNAME>:PORT

Another dirty Solution is ,set Below parameters

 export KC_HOSTNAME_STRICT= "false"
 export KC_HOSTNAME_STRICT_HTTPS= "false"
 export KC_HTTP_ENABLED= "true"

And Start Keycloak like this and access through IPADDRESS

./kc.sh start --http-enabled=false --https-key-store-password=secret --proxy edge

Answer 2

To fix this error add the environment variables:

KC_HOSTNAME_STRICT: "false" KC_HOSTNAME_STRICT_HTTPS: "false"
KC_HTTP_ENABLED: "true" KC_PROXY: edge
