PKIX path building failed Cloud Integration

[ramu_g4]

Hi Experts,

We are getting the connectivity error between iflow (HTTP receiver adapter) and IBM MQ in SAP Integration Suite (Cloud Integration).. It was working fine until yesterday..

Error code on Monitoring: (screenshot2)

Error code HTTP response body:

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..

we have imported all the Root and Issuing certificates shared by IBM MQ team (screenshot1)

Should we also import server certificate of IBM MQ server?

Regards,

Ramu.
