I'm an apprentice at a small company who provide EPOS systems and create e-commerce websites for people. Two of my managers have left and i have been left in charge of everything web-related (including the server that the websites are hosted on), which you could imagine being a lot of stress.
Now for the issue:
The server that all of our websites are hosted on is a Windows 2012 R2 server, running iis 8.5. We have a couple of websites with SSL certificates and all bindings are using SNI, which i am guessing it needs because they are all on the same IP address and port.
It has been fine using these for a while (or i thought it was) but i have just been notified that a plugin, for one of the websites, is not working properly because of SNI being enabled for that website.
The person i spoke to explained that the plugin would only work if SNI was disabled for this site, however, when i disable SNI for the https bindings, none of the other websites with SSL certificates work. All of the other certificates start linking to the website without SNI.
So my question is:
Is there something i can do to allow the websites to work without one of them having SNI enabled?
thanks for any help you can give me.
