Hello, Thanks for the response. However I am able to integrate with Keycloak and Che and while redirecting to che dashboard after authentication by keycloak getting 404 error:

"10.76.0.1 - - [22/Aug/2023:09:07:44 +0000] "GET /dashboard HTTP/1.1" 404 19 "-" "Mozilla/5.0 (iPhone; CPU iPhone OS 16_5 like Mac OS X) AppleWebKit/605.1.15 (KHTML, like Gecko) GSA/277.0.555192628 Mobile/15E148 Safari/604.1" 4340 0.011 [che-che-gateway-8080] [] 10.76.0.59:8080 19 0.011 404 70bf41cc15ec343242e004cd2d7eb61f"

I googled and found two links are close to my issue:

1. https://stackoverflow.com/questions/68111471/getting-404-error-on-eclipse-che-dashboard-hosted-on-gke
2. https://github.com/eclipse/che/issues/21288

In first link it says "The fix is fixing Ingress path from /dashboard/* to /dashboard/". but not able to figure out where I need to do this.

Can you pls help.

Thanks & Regards DK
