I guess the problem is that the cert is for localhost and that does not match the hostname I point my visualvm to.
Question is now: how do I get a valid certificate installed. Help welcome.
Meanwhile I plough through the blogs on that topic.
(What makes me wonder is that what I am trying to do, namely: monitor a GF remotely with VisualVM, seems like a standard use case. But I feel like the only person having problems there. Strange)
Thanks for all the help so far!
