Hello @Ryder005 , I haven't tried deploying Keyloak with Che and DevWorkspace engine myself, but maybe these comments can be useful:

• Devworkspace native auth on Kubernetes - Unauthorized! Configured service account doesn't have access #21049 (comment)
• Devworkspace native auth on Kubernetes - Unauthorized! Configured service account doesn't have access #21049 (comment)

Deploying che on kubernetes is so buggy for me
Another errors has showed up !

[Martj89]

I have the exact same problem the actual version 7.45 and external Keycloak.

If i go to a new inkognito tab in my browser then the first login works.
It seems there is a problem with the redirect after the JWT-Token expires.

Close with Simplify authentication and authorization with a more flexible and lightweight approach and Remove an old authorization flow with Keycloak
