How to resolve peer unverified exception in a secure nifi cluster?

[#1]

I set up a secured NiFi cluster with TLS certificates provided by the organisation.On accessing the UI I am getting the error as "javax.net.ssl.SSLPeerUnverifiedException: Hostname abc.com not verified: certificate: sha256/abc/abcabc= DN: CN=abc.com, OU=Abc Operations, O=Abc Corporation Limited, C=SG subjectAltNames: [abc.com]".I have referred the link https://nifi.apache.org/docs/nifi-docs/html/walkthroughs.html#securing-nifi-with-provided-certificat.... Is there anything I missed to enable peer to peer communication while using SSL?

@tris This is due to your Hostname is not matching in Certificate in my opinion. Have you used IP address in Certificate? If yes please use FQDN and recreate certs.
