It isn't necessary a "good thing", IP based virtual hosting is always better of course.. But.. Do you know any semi-modern browser which doesn't implement SNI?
Thanks a lot everyone for great support.
But this issue is not only in one site or one browser, I have got many different sites which are not supported in some versions of browsers and even in mobile devices also.
So I want to know that issue is in browsers or SSL or programming of sites??
Here I attached 1 more example…
OS - Windows 8.1
Browser version - Safari 5.1.7
As @ahaw021 already said: your site doesn't serve the intermediate certificated, needed to fully chain the end leaf certificate to the root.
Normally, we would just tell you to use fullchain.pem in stead of cert.pem, but that's on regular *NIX based operating systems and you're running Windows.
The tip of @ahaw021 to download and install the intermediate certificate on your client won't suffice: you'll need to install and use the intermediate on your server, otherwise other people using your site won't benifit obviously..
How? Well.. B/c of your OS (Windows), I have no idea. I guess you should search for that yourself I'm afraid..
Yes I always use only fullchain.pem and privkey.pem when I renew it from Linux server. So now I need to check for intermediate certificate while using Windows Server. Right?
That will be your chain certificate, but this isn’t a good solution in comparison to having software provide this for you because eventually the chain certificate for future certificates will change.
