In previous versions, the following steps were executed to resolve the issue :

• Create a certificate chain with the leaf cert at the top, intermediate in the middle and the root at the bottom.
• Save the file in the home directory of the Platform node with a name ( Example : chain.pem )
• Post that, establish a support session to the Platform Node and run the following commands :
  • sudo keytool -importcert -trustcacerts -noprompt -alias "Chain_Alias" -file chain.pem -keystore /usr/lib/jvm/zulu-11-amd64/lib/security/ca
• Post that, re-start the RESTAPI service :
  • sudo systemctl stop restapilayer-service.service
  • sudo systemctl start restapilayer-service.service

Cause

This issue occurs due to a change in the JAVA version in v6.14. In v6.14, the JAVA version installed is 17.0.10. Hence, the location to import the Cert also changes.
