Are you behind a DLP http proxy? I am and the DLP I am behind messes with HTTPS traffic and certs.
I've had to import a trusted cert at system level (also Fedora 31, but running selinux and firewalld). A few java programs I've run had this problem; just had this with JMeter a week or so ago. I used keytool to import my DLP cert and the issue went away (JDK8). That said, I am running NB 12 under JDK 14, and don't recall this with NB12; when I started using it a couple of weeks ago (and don't' recall importing my DLP cert into my JDK14 install).
