Thanks for the response guys. <br />
<br />
I'm looking and there doesn't even seem to be a certificate for me to be able to analyse. Having spoken to their tech department, you're apparently not supposed to see anything other than some text to prove you can get to the site. <br />
<br />
This is the site: <a href="https://api.ereceipts.co.uk/_/version" rel="ugc">https://api.ereceipts.co.uk/_/version</a>&nbsp;. <br />
<br />
When I do this from my own I.E 11, it tries to download a .json file which when I open in Notepad is exactly some text. If I use Chrome on my machine, it doesn't download anything and displays the text as it should. <br />
<br />
But either way, I'm not seeing any ceritificates. Are you able to access the link above to see whether it makes sense that some I.E 8 browsers are not displaying the content?
</div>


<div>
I can access the site using Chrome. &nbsp;If you click on the HTTPS you can inspect the certificate.<br />
<br />
Here it is<br />

<div>
aaah! Okay great. Yes, I can see Cert in Chrome, but not in my I.E as it tries to download that text file rather than displaying it directly. <br />
<br />
I can see that you've got a SHA2 certificate displayed, yes? If that was the case, would it mean that it is less likely to be an SSL issue?<br />
<br />
Thanks for helping out.
</div>


<div>
Correct. &nbsp;SHA256 or SHA2 is correct. &nbsp;The certificate checks out.<br />
<br />
Have you added this site to your &quot;Trusted&quot; zone? <br />
<br />
Assuming you do trust the site.
</div>


<div>
In fact, if you even use online to access and check the ssl cert from this site looks fine.<br />
<a href="https://www.ssllabs.com/ssltest/analyze.html?d=api.ereceipts.co.uk&latest" rel="ugc">https://www.ssllabs.com/ssltest/analyze.html?d=api.ereceipts.co.uk&latest</a><br />
And note the the site supports only TLS1.0 and above so if browser cannot do that and does sslv3 and below it will not be able to access.
</div>


<div>
It is odd that you would suddenly get this today with XP. &nbsp;However, this is only going to get worse as websites transition to TLS security and decrement SSL.<br />
<br />
What does your connection tab show in XP using Chrome browser for that Certificate?<br />
<br />

<br />
<br />
Do you have TLS 1.0, 1.1 checked on the Advanced Tab under Internet Tools, Options?
</div>

<div>
Do you have TLS 1.0 checked on the Advanced Tab under Internet Tools, Options?<br />
<br />
This is for IE.<br />
<br />
IE supports TLS 1.0 but you really need to migrate these machines off XP<br />
<br />

</div>


<div>
Okay on Chrome on my machine only (running Windows 7), it shows the same certificate as your pictures did. <br />
<br />
I definitely have TLS 1.0 checked on both machines. I followed the link you sent to me and can see that it is indeed trusted. I just don't get why one machine gets there and the other one doesn't. Could it even be that one version has some updates which permit it to get to the site?<br />
<br />
(I want to migrate these, but they sit in our stores across different parts of the country which will take some time).
</div>


<div>
Either way, I'm going to get these off the estate guys. Apparently, I've just spoken to the department for this website and they confirmed that I.E 8 does indeed have a lot of issues. <br />
<br />
I'll close this, but again this has helped me greatly with the knowledge I've gained. Cheers guys.

<div>
Just one thing, you know when you analysed the website via the link, how did you use the website to workout that things had to be TLS 1.0 and above. Was it in the section under 'Protocols' which tells you the different version of TLS it supports?
</div>


<div>
Actually, I go in to detail in my article for TLS/SSL operating system hardening best practice.<br />
<a href="https://www.experts-exchange.com/articles/25021/Citrix-SSL-TLS-Vulnerabilities-and-Operating-System-Hardening.html" rel="ugc">https://www.experts-exchange.com/articles/25021/Citrix-SSL-TLS-Vulnerabilities-and-Operating-System-Hardening.html</a><br />
<br />
I wrote this for Citrix, Server 2008 R2, and workstations (Windows 7) but all the core principles the same.<br />
<br />
I think it would answer all your questions and if it does not I would be interested to know and might add that content.
</div>


<div>
Was it in the section under 'Protocols' which tells you the different version of TLS it supports?<br />
<br />
Correct, Protocols.

Hi guys, <br />
<br />
We have two Windows XP machines. There's Internet Explorer 8 on them both. They sit in our stores. <br />
<br />
Both of them are going via the same firewall, and all rules are permitting them to go out to this external site. However, one of them gets the &quot;there is a problem with this website's security certificate&quot;, which at least you can click onto continue and get to the require page. However, the other PC with the same configurations gets a &quot;page cannot be displayed&quot;. <br />
<br />
I've checked SSL settings and both have TL1.0 on and SSL3.0 ticked. <br />
<br />
Any ideas what it could be?<br />
<br />
Thanks for helping<br />
Yashy

Microsoft Windows XP is the sixth release of the NT series of operating systems, and was the first to be marketed in a variety of editions: XP Home and XP Professional, designed for business and power users. The advanced features in XP Professional are generally disabled in Home Edition, but are there and can be activated. There were two 64-bit editions, an embedded edition and a tablet edition.

HTTPS is a protocol for secure communication over a computer network which is widely used on the Internet. HTTPS consists of communication over Hypertext Transfer Protocol (HTTP) within a connection encrypted by Transport Layer Security (TLS) or its predecessor, Secure Sockets Layer (SSL). The main motivation for HTTPS is authentication of the visited website and to protect the privacy and integrity of the exchanged data. HTTPS is widely used for protecting page authenticity on all types of websites, securing accounts and keeping user communications, identity and web browsing private.

Windows 7 is an operating system from Microsoft. Features include multi-touch support, a redesigned Windows Shell with a new taskbar, referred to as the Superbar, a home networking system called HomeGroup, and performance improvements.
