Do you have the explanation of this error?

According to the SSL Labs test the site looks very reasonable. https://www.ssllabs.com/ssltest/analyze.html?d=www.re-guide.jp

Why it doesn't work with Firefox, I don't know. I can only guess about a server configuration error. Try to contact the web site owner.

The site doesn't work in Chrome either, so it's unlikely that this is a Firefox issue.
