Invalid SSL certificate found. PKIX path building failed

Hi,

We are getting below issue on Portal for ArcGIS version 10.5.1.

Issue:

Invalid SSL certificate found. PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

Initial time the Portal for ArcGIS is working fine but SSL Certificate got expired then we are facing the issue while doing analysis, even we change the logs to debug all the log file is filed with the text which i have pasted above as issue.

Now we upload the new certificate even though issue not resolve.

Please suggest to mitigate the issue.

Before renew the Portal is already working with Analysis tool on the Map Area.

All the logs file is showing below message only.

"Invalid SSL certificate found. PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target"
