We are experiencing the following issue when trying to configure standby while using the enterprise CA certificate for HA cluster, while using the self-signed certificate we are not having this issue. We have validated the certificate settings and it has the correct CN, SANs as recommended in CyberArk documentation
Error message below
"pg_basebackup -D /var/lib/postgresql/9.4/main -d host=\ port=5432\ user= application_name=standby_\ sslmode=verify-ca\ sslrootcert=/opt/conjur/etc/ssl/ca.pem\ sslcert=/opt/conjur/etc/ssl/conjur.pem --xlog-method=stream --verbose --progress
pg_basebackup: could not connect to server: received invalid response to SSL negotiation: H"
Any suggestions on correcting this would help
