GitHub actions not able to find valid SSL certificate from maven.apache.org

When attempting a build using GitHub Actions I intermittently get the following error:

Non-resolvable parent POM for org.apache.datasketches:datasketches-memory-root:2.1.0-SNAPSHOT: Could not transfer artifact org.apache:apache:pom:23 from/to central (Central Repository:): transfer failed for https://repo.maven.apache.org/maven2/org/apache/apache/23/apache-23.pom and ‘parent.relativePath’ points at wrong local POM @ line 27, column 11: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target → [Help 2]

Full details at: Removed NioBits and NioBitsFields. Plus improving some javadocs and a · apache/datasketches-memory@44d311f · GitHub

The cert on repo.maven.a.o looks fine.

Any help would be appreciated.
Thanks.
