[Q] 9.1 amd64 openJDK11 error on certificates

[ts1000 <ts1000%rad2know.net@localhost>]

Hello,
I have a java project organized by Gradle.
First thing that gradle does, is it downloads dependencies.

But that first step is not working on netBSD-9.1 amd64
I tried with pkgin, as well as building openjdk11 from source.
Error is the same.

I also installed, with pkgin,
ca-certificates-20200601
mozilla-rootcerts-1.0.20200529nb1

But that did not help. Would appreciate any pointers on where to look


The error I am getting is:
