To resolve this issue, delete the expired certificate from the Keystore and/or the Truststore.
Complete all steps, as only one store may contain expired certificates.
cat /storage/vcops/user/conf/ssl/storePass.properties
keytool -list -v -keystore /data/vcops/user/conf/ssl/tcserver.keystore
keytool -delete -alias <alias_name> -keystore /data/vcops/user/conf/ssl/tcserver.keystore -storepass <keystore_password>
keytool -list -v -keystore /data/vcops/user/conf/ssl/tcserver.truststore
keytool -delete -alias <alias_name> -keystore /data/vcops/user/conf/ssl/tcserver.truststore -storepass <truststore_password>
If a needed certificate is deleted, it can cause issue with vRealize Operations Manager itself, or collections.
Take a snapshot of the vRealize Operations Manager nodes before proceeding with the Resolution section.
If an old certificate is determined to be in use by an installed Management Pack, see Remove a solution from vRealize Operations to remove the Management Pack.
Alternatively, you can try upgrading the Management Pack if an upgrade is available.
