Problem with HTML validator tool, "SSL negotiation failed" error from HTML validator tool Options

[daa137]

I'm trying to use the HTML validator tool and getting the error "Error retrieving https://www.nesfa.org/: SSL negotiation failed:" with no further information.

This tool used to work on this site (www.nesfa.org, hosted at DreamHost.com), and I've successfully accessed the site from several different computers since I noticed this problem. I'm not sure when the problem first appeared since my use of this tool is sporadic; it's been failing for at least the past several weeks.

How can I get this problem diagnosed and fixed?

Thanks in advance,

Dave
