LGTM
Seems to be the case since CoreDNS v1.9.4 e0dead4
The plugin dropped the actual error message from the log, so the log becomes completely useless. Before: ``` [ERROR] plugin/kubernetes: error Failed to watch ``` After: ``` [ERROR] plugin/kubernetes: Failed to watch: failed to list *v1.Namespace: Get "https://10.96.0.1:443/api/v1/namespaces?limit=500&resourceVersion=0": tls: failed to parse certificate from server: x509: SAN dNSName is malformed ``` Signed-off-by: Andrey Smirnov <andrey.smirnov@siderolabs.com>

Before:
After:
1. Why is this pull request needed and what does it do?
Fixes a bug which makes troubleshooting next to impossible.
2. Which issues (if any) are related?
None, but due to Go 1.25.2 changes to strict SAN validation, CoreDNS might fail to access Kubernetes API on version 1.13.1.
3. Which documentation changes (if any) need to be made?
None.
4. Does this introduce a backward incompatible change or deprecation?
Nope.
