[Bug]: IPv6 Compatibility Issue for Dashboard Backend Server

[chaturvedi-kna]

Is there an existing issue for this?

• I have searched the existing issues

Deploy type

Downstream version (eg. OpenShift AI 2.4)

Version

2.13.1

Current Behavior

The ODH Dashboard backend encounters two critical issues when deployed in an IPv6-only environment:

1. Readiness/Liveness Probe Fails:
   The server binds only to 0.0.0.0 (IPv4), which causes connection failures when the liveness probe attempts to connect to an IPv6 address.

2. Hostname/IP Validation Failure:
   The backend throws errors due to improper handling of IPv6 addresses in API requests, specifically missing brackets around IPv6 addresses in URLs.

Expected Behavior

• The backend should bind to an IPv6-compatible address (::) or dynamically detect the appropriate interface.
• IPv6 addresses in API requests should be enclosed in square brackets ([]) to avoid hostname validation issues.

Steps To Reproduce

1. Deploy the ODH Dashboard in an IPv6-only OpenShift cluster.
2. Observe the following error in the Kubernetes event logs:
   Liveness probe failed: dial tcp [fd02:0:0:1::13c]:8080: connect: connection refused
3. Observe the following error in the backend logs:
   Hostname/IP does not match certificate's altnames: Host: fd02. is not in the cert's altnames
