Hi,
I'm trying to run an Ant build on one my Linux buildengines, but the following error shows up:
<b>
Unable to update last contact time for engine: com.ibm.team.repository.common.transport.TeamServiceException: CRJAZ0099I HTTP error &quot;com.ibm.jsse2.util.g: PKIX path building failed: java.security.cert.CertPathBuilderException: unable to find valid certification path to requested target&quot; accessing URL &quot;https://&lt;IP&gt;:9443/jazz/service/com.ibm.team.repository.common.internal.IRepositoryRemoteService&quot;.

</b>

Has anyone seen this before? How can I fix this error? Thanks.

Here's the complete logfile:
