Hi All, We use TeamCity 7.1.5. I updated TeamCity Server site certificate ( replaced server.p12 file with new one) for new time period and TeamCity Server lost connection with single Agent. Agent status is Disconnected, Authorized, Enabled. With WEB Browser I navigated to TeamCity site and made sure new certificate is valid. Into teamcity-agent.log file I see many simular messages, for sample: [2014-03-20 16:37:11,694] WARN - jetbrains.buildServer.AGENT - Ping problem: Call https://oursite/RPC2 buildServer.ping: javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target How I can fix this Agent connectivity problem with new certificate? With old site certificate TeamCity worked properly.
Thank in advance, Shimon
P.S. I see difference in Details of old and new certificate. Old Certificate Signature Algorithm is PKCs #1 SHA-1 With RSA Encryption. New Certificate Signature Algorithm is PKCs #1 SHA-256 With RSA Encryption.
