      The latest site you linked shows same message here, on Opera dev / W10.

      But for sites, giving you 'unsupported protocol' message, this can be problem with site certificate - few sites use free EC (elliptic curve based) certificates, which can not be checked using windows XP internal crypto libraries. For these sites, Firefox based browsers (which use internal crypto) are the only way on XP - all other browsers (IE, Chrome, Opera and derivatives) use windows crypto library. Well, old Opera (up to 12) may sometimes work too, if such sites allow fallback without encrypting connections, but this is not reliable way.

      You have to check with other browsers (Chrome, IE, Firefox) - this helps to pinpoint specific issues.

        This is one of the websites I can no longer access, it's a Japanese site for uploading images of civilian and military aircraft- http://appdc.orz.hm/up/index/1

        I've tried with Opera, Firefox and Chrome and none was able to load that page.

          The site also fails in Firefox, Qupzilla, Opera 12.18, and Vivaldi. All error messages indicate the connection was refused, in Qupzilla's case indicating "the server is refusing the connection', which may or may not refer to the appdc.orz.hm server itself. Whatever is going on with the site, it's not related to your browser or cert store per se. It's possible the server is blocking incoming traffic or experiencing DDOS attacks... it's hard to say.

          Do you have another site that is causing you similar problems?

            One of the sites I used to be able to see on opera works fine on firefox, the other site I can no longer access is adult orientated so I don't want to put the URL here in case any minors see it. The one I really miss is the Japanese aviation site though, I wonder if it's anything to with the ISP?

              There's something wrong with the URL: http://appdc.orz.hm/up/index/1

              In attempting to get a 'who-is' for the URL, it comes up as an unrecognizable domain name, which means a browser DNS lookup attempting to convert it to an IP number to complete the connection will fail... hence the connection attempt will fail. Are you sure the URL you provided is completely accurate?

              From the wiki: ".hm is an Internet country code top-level domain (ccTLD). Ostensibly, the domain is reserved for the Heard and McDonald Islands, uninhabited islands in the southern Indian Ocean that are under the sovereign control of Australia; Australia instead uses an .aq domain for its sites related to Heard and McDonald Islands."

                The URL is exactly as I have it bookmarked, nothing there has changed. I'm at a loss how to explain it, it was working fine and I had no problem accessing the website until a few weeks ago...

                  It appears there is a fee-based .hm domain registry operating out of Colorado, USA (at least their phones/FAX are there), meaning that people can register a website having a .hm end-code. As it turns out, the orz.hm domain is owned by Agora Inc, and hosted by K-Opticom Corporation. As of February 2016, orz.hm received 96% of its traffic from within Japan. The orz.hm domain owner then sub-leases various website names (eg: appdc.orz.hm, minecraft9.orz.hm, g2labo.orz.hm, etc) to interested parties. The g2labo.orz site connects, the minecraft9 site fails connecting (the gamesite was banned by Microsoft), and the appdc site connection problems you already know about.

                  Given the mixed results, the impression I get is that the appdc site/server is down, there is a DNS lookup contamination issue for the URL, the site is being DDOS'd, or either the domain-owning company or the site-owning company is having problems of their own. The only search-engine results I can turn up for the URL you provide are a handful of Japanese-language posts and a number of photo-images on other sites linking the photo-related URL's back to your URL - and some of those pictures are definitely off-topic for an aircraft-photo website. That indicates some spamming/misuse-of-site issues that were occurring for the URL's owner(s).

                      That's the first time I've ever been accused of knowing too much!

                            UPDATE
                            After noticing that Opera had updated to the latest version, out of curiosity I decided to try one of the websites that I had no longer been able to access, BINGO!, it worked! I could now access the website again. Cue several hours later when I tried again, back to normal with a blank screen and no access! This is now officially infuriating, because if nothing else it proves that the website is still active, just that I can't access it again, what could possibly have happened in those few short hours between being able to access it again and then suddenly unable to once more?

                            -Daz

                            p.s. I'm a little reticent about posting the name of the website because of it's adult content.
