Description of problem:
The Dev Spaces operator is not functional in IPv6 single stack deployments. Specifically, the devspaces-dashboard pods remain in CrashLoopBackOff state due to the following TLS error:
2025-12-01T22:28:53.048951936Z Error [ERR_TLS_CERT_ALTNAME_INVALID]: Hostname/IP does not match certificate's altnames: Host: fc00. is not in the cert's altnames: DNS:kubernetes, DNS:kubernetes.default, DNS:kubernetes.default.svc, DNS:kubernetes.default.svc.cluster.local, DNS:openshift, DNS:openshift.default, DNS:openshift.default.svc, DNS:openshift.default.svc.cluster.local, DNS:fc00:30::1, IP Address:FC00:30:0:0:0:0:0:1 2025-12-01T22:28:53.048951936Z at Object.checkServerIdentity (node:tls:316:12) 2025-12-01T22:28:53.048951936Z at TLSSocket.onConnectSecure (node:_tls_wrap:1687:27) 2025-12-01T22:28:53.048951936Z at TLSSocket.emit (node:events:524:28) 2025-12-01T22:28:53.048951936Z at TLSSocket._finishInit (node:_tls_wrap:1076:8) 2025-12-01T22:28:53.048951936Z at ssl.onhandshakedone (node:_tls_wrap:862:12)
Prerequisites (if any, like setup, operators/versions):
Steps to Reproduce
1. Deploy OpenShift 4.20.0 in an IPv6 single-stack environment
2. Install the Dev Spaces operator. In our environment, we installed:
oc get csv NAME DISPLAY VERSION REPLACES PHASE devspacesoperator.v3.24.0 Red Hat OpenShift Dev Spaces 3.24.0 devspacesoperator.v3.23.0 Succeeded devworkspace-operator.v0.37.0 DevWorkspace Operator 0.37.0 devworkspace-operator.v0.36.0 Succeeded
Actual results:
The devspaces-dashboard pods remain in CLBO status
oc get pods -n openshift-operators | grep devspaces-dashboard devspaces-dashboard-9d45c475-w96wd 0/1 CrashLoopBackOff 22 1h devspaces-dashboard-b85f54965-mh6wf 0/1 CrashLoopBackOff 22 1h
Expected results:
The devspaces-dashboard pods start normally
Reproducibility (Always/Intermittent/Only Once):
Always
