HTTP 404 after installing an SSL Certificate

  • Artigo

This article has been moved to its new home here: https://benperk.github.io/msdn/2014/2014-02-http-404-after-installing-an-ssl-certificate.html

I was configuring an SSL certificate and once complete, when I attempted to access the website using https://localhost I started receiving a 404 error as shown in Figure 1.

Figure 1, 404 HTTP Status after installing an SSL Certificate

I tried some shots at troubleshooting the issue using Failed Request Tracing and LogParser to view the IIS logs, but didn’t get a Failed Request Trace and I found no entry in the IIS logs.  I confirmed that there was a default document in the websites directory and even browsed right to it and still got a 404.  Obviously, this is not a File Not Found issue.

My bindings were similar to that shown in Figure 2.

As the issue was not being logged into the IIS logs, I concluded that the issue must be happening at the HTTP level.  So I looked in the HTTP Error logs located by default at c:\windows\system32\logfiles\HTTPERR and did find the error being logged, a subset of that is shown below.

2013-11-12 13:15:58 ::1%0 61522 ::1%0 443 HTTP/1.1 GET / 404 - NotFound -
2013-11-12 13:16:23 ::1%0 61526 ::1%0 443 HTTP/1.1 GET / 404 - NotFound -
2013-11-12 13:17:08 ::1%0 61533 ::1%0 443 HTTP/1.1 GET / 404 - NotFound -

After some effort and just looking at the bindings again, I determined that the reason for the error was due to the fact that I was accessing the website using https://localhost for which there was no binding.  I.e. there was no binding for *:443 or localhost:443.

I should note that I added the following entry to the HOSTS file so that https://invalidhostname did indeed render as expected.  Ex. “127.0.0.1 invalidhostname”

I updated the bindings so they reflected that shown in Figure 3, so that when I now made the request, the 404 was gone.

This was a problem that took me some time to resolve, so just sharing in case it saves others some time.

    Thanks - I've just had a similar problem and this helped me fix it.Am I right in thinking that when using TLS the host header is basically ignored as you can only have one certificate per IP address (I seem to remember setting up sites in Apache this way)?
