Mismatched Address Certificate Error Exchange 2013
up Here's how it works: Anybody can ask a question Anybody can answer The best answers are voted up and rise to the top Why does my wildcard SSL certificate cause a domain mismatch error on a second level subdomain? up vote 6 down vote favorite 2 I have a server https://www.groups.example.com - in FireFox I get the "This ssl certificate error mismatched address Connection is Untrusted" message and the "technical details" say www.groups.example.com uses an invalid security certificate. The certificate is only valid for the following names: *.example.com, example.com (Error code: ssl_error_bad_cert_domain) What other info do I need to provide in order to resolve this? Just getting confirmation of setup but am 99% sure it's Linux and using VHOSTS. Will update question as soon as this is confirmed. Is it the fact that www.groups.example.com is seen as having 2 levels of subdomains? The issuer is DigiCert ssl https ssl-certificate share|improve this question edited Nov 18 '14 at 20:50 Charles 8201821 asked Nov 18 '14 at 14:46 pee2pee 13615 1 I'm sure it's the two levels of subdomain that are the problem, and I'm fairly sure this is a duplicate question - but I can't put my hand on the original question at the moment. –MadHatter Nov 18 '14 at 14:51 You can't use a subdomain of the wildcard part and have a match. You would need to use SANs. Furthermore, mydomain.com is not t

Firefox: "www.example.com uses an invalid security certificate." or mismatched address certificate error ie11 "The certificate is only valid for the following names: www.otherdomain.com , otherdomain.com" This how to fix mismatched address certificate error 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 ssl certificate hostname mismatch 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, you connect http://serverfault.com/questions/645230/why-does-my-wildcard-ssl-certificate-cause-a-domain-mismatch-error-on-a-second-l 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 with the https://www.digicert.com/ssl-support/certificate-name-mismatch-error.htm 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 visit a fake (and pote
Kumar PandayJune 12, 20133 0 0 0 Yesterday one of my colleagues came up to me with a simple problem regarding wild card certificates. I gave him the solution immediately, but it had to take a lot of convincing to do. This shows that https://blogs.msdn.microsoft.com/kaushal/2013/06/12/working-with-wild-card-certificates/ there is a lot of confusion around how wild card certificates work. https://www.instantssl.com/ssl-faqs/ssl-certificate-errors.html For first time readers, wildcard certificates are server certificates which contain a wildcard (*) as part of the hostname. They offer a great advantage as one hostname containing a wildcard can match multiple hostnames provided they satisfy the condition. Typically the Issued To section of the certificate will contain a hostname certificate error with a wildcard. There are real world examples like Facebook and Yahoo: SAN certificates can also contain wildcard hostnames. They are a parent set, so a SAN certificate is also a wildcard certificate if it contains a hostname with a wildcard as shown in the above image. ****CONFUSION**** As only one cert can be bound to a specific IP+Port, regular certificates were mismatched address certificate not very helpful. Wildcard certificates provided solution to this problem. Thought not a full-fledged solution to the problem. It provided some relief. The admins could have a certificate issued to *.contosso.com and then have hostnames configured accordingly. However this gave rise to some confusion. Even though this is clearly documented in the RFC’s. I have still seen many getting confused on this. Consider a certificate issued to *.contosso.com. If this has to be configured any web server, then a question arises. What all valid hostnames can be configured with the above certificate? Lets take a look at the below table SSL Certificate issued to Host Name configured on the web server Is valid? 1 *.contosso.com marketing.contosso.com ✔ 2 *.contosso.com hr.contosso.com ✔ 3 *.contosso.com apps.developers.contosso.com ❌ 4 *.contosso.com 123.test.beta.contosso.com ❌ Looking at the above table you should have understood that the wildcard character allows only one single domain as an addition to the hostname. If you were to configure a host name as per 3 & 4 on IIS for a cert issued to *.contosso.com, then the client browser would throw an error indicating address mismatch.
of websites to provide security and confidentiality for online transactions. However, there are a few problems that can occur with their deployment that cause error messages to be shown to website visitors. This page aims to provide an overview of the most common SSL errors along with suggestions on how to fix them. The SSL certificate for this website is not trusted Site uses a self-signed certificate Intermediate certificate(s) not installed Certificate Name Mismatch Error Mixed content Error The SSL certificate for this website is not trusted An internet browser will state that a website certificate is untrusted if that certificate has not been signed by a trusted Certificate Authority. In order for a browser to accept a certificate, it must be able to link it to a 'trusted root certificate'. Trusted root certificates are embedded into popular browsers such as Internet Explorer, Firefox, Chrome and Comodo Dragon. These root certificates are used as trust 'anchors' to verify the legitimacy of all website certificates that the browser encounters. If a browser encounters a certificate that is not signed by one of these roots, then it will state it is untrusted and visitors will see an error message like the one above. Most trusted root certificates in a browser are owned by an accredited Certificate Authority (CA). When a CA signs the certificate of a website, it is effectively 'linking' that website's certificate to one of their trusted roots in the browser certificate store. For security reasons, most CA's do not sign end-entity/website certificates directly from the root, but will instead use an 'intermediate certificate' to create a 'chain of trust' to the root. In this system, the root certificate will sign the intermediate and the intermediate is used to sign the certificates of individual websites. 'Untrusted' errors, therefore, are usually caused for one of two reasons: Site uses a self-signed certificate In many cases, this is because the website is using what is known as a 'Self Signed Certificate'. As the name suggests, a self-signed certificate is one that the website owner has generated and signed for themselves using their webserver software. Therefore, the certificate is not associated with any 'trusted root' in the browser's certificate store and the browser will display an 'untrusted' error. Self-signed certificates do have t
