Certificate Errors

When the browser is unable to verify SSL certificates returned by a server, an SSL certificate error occurs. As shown below, when the error occurs, your website is blocked and a warning appears telling the user it cannot be trusted. These warnings can have a negative impact on your website’s reputation.

Several factors can cause the above error. Here is a partial list.

Self Signed Certificate In Certificate Chain

This is a good thing, since it warns you against a man-in-the-middle attack, which may also happen if your certificate is self-signed.

Err Cert Authority Invalid

There are other situations where the NET::ERR_CERT_AUTHORITY_INVALID error may occur, including when your SSL certificate is not recognized by your browser, or if your SSL certificate was self-signed. You will have to obtain your SSL from an authorized Certificate Authority in both of these cases.

Certificates cannot be validated in Skype: One of the most common causes of this error is that Skype is unable to validate the certificates stored in its cache or to retrieve certificates from its server. This happens because the cached certificates may have been corrupted and the cached credentials may not work or may be out of date. Another reason why certificates are not properly validated is that the certificate chain is not recognized by Skype and the validation process fails.

Ssl Certificate Problem: Certificate Has Expired

Your site can still communicate with other websites if it has an expired certificate on the server even if it has a valid SSL certificate for the SSL connection between the server and the browser. The root certificate of the server must be updated if you receive the error 60SSL certificate problem: certificate has expired.

Outdated Lync client: If the Lync client installed in Windows is not up to date, you may receive this error due to an outdated/unsupported version of the Lync client with a version of Skype installed. This may be the reason why you are getting this error.

In this error message, it indicates that the CA certificates for the root and intermediate CA are not in the storage system and need to be imported first. Follow this procedure on importing certificates for well-known CAs.

Outdated Microsoft Services Connection Wizard: Another possible reason for this error may be that the Microsoft Services Connection Wizard installed on your Windows computer is outdated, which may not be compatible with the version of Skype for Business you are using.

Certificate For This Server Is Invalid

I am having difficulty connecting to the iTunes Store on my iPod. I receive the message “you cannot connect to the iTunes Store” when I select the App Store. If I try the iTunes icon, I get the error “this certificate is invalid.” The server you are connecting to may be pretending to be “,” putting your confidential information at risk.

Unattended DNS cache in Windows: If you haven’t flushed the DNS cache in Windows for some time, your DNS trash may be preventing Skype from connecting to its servers and performing the certificate validation process.

You can try the following solutions if you are experiencing this Windows error. Since each solution is specific to the cause, it is possible that not all will work for you, but we hope you will be able to find one that does.
