Ssl Certificate Error Mismatched Address
error on self-signed ssl certtificate up vote 2 down vote favorite I have a self-signed ssl certificate that I am trying to use on my Windows 7 development IIS7 machine.

I’ve been through numerous blogs and postings and have tried to create the certificate using many different techniques. I've mismatched address certificate error ie11 tried using both my machine name and localhost for the certificate but I get the same error. These are the two I have followed most closely: http://blogs.technet.com/b/sbs/archive/2007/04/10/installing-a-self-signed-certificate-as-a-trusted-root-ca-in-windows-vista.aspx http://www.robbagby.com/iis/self-signed-certificates-on-iis-7-the-easy-way-and-the-most-effective-way/ This is my certificate in the MMC console under Trusted Root Certificates Authorities: The signature matches the one assigned in IIS: And my site is bound to that certificate: Why do I continue to get the error and how can I fix it?

How To Fix Mismatched Address Certificate Error
at what the browser reports about the certificate error. In the image below, we clicked ssl certificate domain name mismatch the certificate error and see the root cause displayed. SSL errors are usually caused by one of three things: Untrusted Root Certificate -- how to fix ssl certificate name mismatch error Fix: Install Root Certificate (Certifying Authority) Mismatched certificate-URL host name -- Fix: Add Hosts File Entry Can't get past SSL error in Console -- Fix: Tweak Registry Setting Install Root Certificate (Certifying Authority) Most SSL certificates come http://serverfault.com/questions/393363/mismatched-address-error-on-self-signed-ssl-certtificate from a well-known certifying authority like Verisign, Thawte, GeoTrust and others. These companies charge for their certificates, which enables them to do some level of check on the company requesting the certificate. Because of this, browsers recognize certificates signed by these Certificate Authorities. Self-Signed Certs With self-signed certs, a Certifying Authority was not involved. That means the product has to sign it's own SSL certificates, and therefore be its own Certifying Authority. Since the browser https://www.poweradmin.com/help/sslhints/ doesn't know about this new Certifying Authority, it shows warnings indicating it doesn't know whether to trust the SSL certificate or not. To make the browser stop displaying the warnings, you have to install the new Certifying Authority certificate into the browser as a Root CA or Trusted CA. Be careful -- only install a new Certifying Authority when you know who it is because you are telling the browser to trust SSL certificates from that authority. In this case, the Power Admin product created the new Certifying Authority on your computer. No other computer has that Certifying Authority. For instructions on installing a new Certifying Authority in popular browsers, choose your browser below: Instruction for installing in Internet Explorer Instruction for installing in FireFox Instruction for installing in Google Chrome Mismatched Address - Add Hosts File Entry When the SSL certificate was made, it was created using the computer's name, localhost and 127.0.0.1. In the examples above, that means we could go to https://dnvista or https://localhost or https://127.0.0.1 and the host name in the URL would match the host name listed in the SSL certificate. If you access the page using the host name in the certificate, mismatched host address errors will go away. If you can't access it with the host name in the certificate (perhaps because an external host name i
was issued to a domain other than the you accessed. Internet Explorer: "The security certificate presented by this website was issued for a different website's address." Firefox: "www.example.com uses an invalid security certificate." https://www.digicert.com/ssl-support/certificate-name-mismatch-error.htm or "The certificate is only valid for the following names: www.otherdomain.com , otherdomain.com" This happens when the common name to which an SSL Certificate is issued (e.g., www.example.com) doesn't exactly match the name displayed in the URL bar. Any difference will cause the web browser to halt and display a name mismatch error. This error can happen even if the correct certificate is installed properly. For example, certificate error you connect to the website via the IP address or an internal name but the certificate was issued to the fully-qualified domain name (or vice versa). It is also possible that a self-signed certificate could be installed instead of a server-specific security certificate issued by a Certificate Authority (like DigiCert), or that the domain name was misspelled in the request. If your website is secured by a certificate mismatched address certificate with the name www.example.com you will receive this error if you connect using any of the following names: example.com example.local 208.77.188.166 10.1.1.7 Even though all of the above addresses would get you to a site with a valid certificate, you could still get a name error if you are connecting to a name other than the one that the certificate was issued to. DigiCert's Multi-Domain (SAN) Certificates were designed to resolve this problem by allowing one certificate to be issued to multiple names (i.e., fully-qualified domain names or IP addresses). To check your certificate for a name error, we recommend that you use our SSL Certificate Checker. Enter your domain in the server address box; if the certificate name doesn't match, you will get an error message stating "Certificate does not match name example.com". Below are a few more warning messages for different browsers. Google Chrome: "This is probably not the site you are looking for! You attempted to reach www.site.com, but instead you actually reached a server identifying itself as othersite.com. This may be caused by a misconfiguration on the server or by something more serious. An attacker on your network could be trying to get you to vi
