Do you use self signed SSL certificates in your JIRA?  You may want to ensure your client can trust this certificate.  There is a number of pages when similar issues have been discussed and resolved, see:

• https://answers.atlassian.com/questions/305588
• https://confluence.atlassian.com/display/JIRAKB/Unable+to+Connect+to+SSL+Services+due+to+PKIX+Path+Building+Failed+sun.security.provider.certpath.SunCertPathBuilderException
• https://confluence.atlassian.com/display/JIRAKB/Outbound+SSL+Connections+flooding+the+logs+with+exceptions

Hope that helps,
