Hi Levente,

Sorry for my delay in replying, these tips are very helpful.

The plugin is out of date in the interpreter VM, and I get a certificate

With a Cog VM, I get a primitive failure in SqueakSSL>>primitiveSSLCreate.

So in both cases it is presumably a plugin issue.

Thanks for explaining, I understand it now.

Yes for sure.

Thank you!
