Just ran into this myself. Posting stack trace, MWE reproducer and versioninfo() for sake of completeness.

I tested the fix (9fb67a1) from @KristofferC and it works.

#711

Please merge this @KristofferC .

When used after building a shared library, it seems to try to find the cert.pem file from the relative path to the Cpp main executable that loads this library, instead of relative to the julia lib path. Don' t know if it is easy to fix. Currently adding a symlink works.
