I get the same error which suggests to me that the url needs correcting. Other possible fixes can be clearing the DNS cache, the browser cache or cookies (but they wouldn't apply in my case). The Mozilla page warns against repeating a "bad request".

I worked for an internet company and worked on https papers to advise business groups. I have tested the logical combinations in terms of getting the site to show across the board. And it's not.

Like I said to the support rep at the hosting company, if I do actually get a request in terms of supplying a fix to a site visitor, I don't want to be saying "change your browser", possibly I do want to be seeking legal advice in terms of "Blocking".

I suggest you find a tech representative who isn't going to cost you money rather than supplying reps that are a waste of times in terms of information supplied.

Interesting.... It works in Chrome. see screenshot

The other links work on the site, but it's just the blog that fails. Someone more Dev savvy will have to chime in. What does this mean? --> Your technical support key is: 49c3-96c8-582e-c5e4 Maybe someone on the server side can look at the logs.

I've checked it out on Windows 10 and on XP - which I did a day ago. It's actually accessible on XP so there's a couple of variables that have changed. The version of Firefox and the Windows 10 platform.

So it's still not resolved but none the less annoying to say the least.

And good news, it has been resolved one of the plug ins via the blog which has a range of security levels was found to be the culprit, I'm fairly surprised, although I was starting to suspect something to do with the blog. Although I found it difficult to believe that Firefox would be blocking Blogs. The setting does suggest that if it's that high it might block "Some people", possibly "the people" are Firefox users.
