[IPT] error in communication with gbif registry

[Rui Figueira]

Dear IPT list,

My IPT 2.7.6 installation on a debian server with java JRE 8 and tomcat7 
show the following error:

An IO error occurred while trying to communicate with the GBIF Registry. 
[https://gbrds.gbif.org/registry/network.json]

When I did a restart of the tomcat service, I got the following error in 
the log file

ERROR 03-Apr-2024 17:29:35 [org.gbif.ipt.service.admin.impl.VocabulariesManagerImpl] - An IO error occurred while trying to communicate with the GBIF Registry. [https://gbrds.gbif.org/registry/thesauri.json]
org.gbif.ipt.service.RegistryException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

As a consequence, the IPT is unable to show any of the existing resources.

Have you seen this error, and know how to solve it? Notice that the 
server has no ssl certificate installed.

Thanks,

Rui
