Fully validated, Enterprise SSL Certificates
Latest News:
Common Frequently Asked Questions
This error normally occurs when the root and intermediate certificates
(available from our website) are not installed on the web server hosting
the site.
Once these certificates are installed on the web server this issue should
be resolved
Full installation instructions for the most common web servers can be found by following the link below:
http://www.enterprisessl.com/ssl-certificate-support/cert_installation/ssl-certificate-index.html .
This error only occurs when the certificate has expired or is not valid
yet.
(This can also occur when the client system is set to the wrong time and
date)
The certificate common name must match the site name EXACTLY or this
error will occur.
To secure a site "www.domain.com" you will need a common name
of www.domain.com
the only exception to this is the wild card certificate which can secure
*.domain.com which secures all sub-domains of the domain.com
The easiest way to correct this if a mistake it made is to send a new CSR, with the corrected common name, along with your order number to support@comodogroup.com and we will regenerate the certificate for you.
This error occurs then there are "Https://" and "http://" reference's to items within a web page this can be resolved but changing these to the correct reference for the type of page if this is on a secure page these will need to be "https://" and on a non secure page they will need to be referenced as "http://"
There are a few things that can cause this error, the most common ones are listed below:
1 : There is a firewall / router on your network not allowing traffic
on the SSL port.
2: The private key for your certificate does not match or is not associated
correctly with the certificate
3: The server itself is not configured to run SSL on the desired port,
ie the port to listen on has not been entered
4: There is a DNS error on the network or an incorrect DNS mapping.
This error occurs if :
1. You are using the Trust Logo on a domain that you had not purchased
it for.
2. The Trustlogo part of the order has not been issued yet.
3. The Javascript is requesting the wrong details. ie : The Javascript
is different if you have a Comodo issued SSL certificate or not.
NOTE: The Trust Logo can only be used on a domain that it is purchased for.
This error can be caused by several incorrect fields within the CSR or the CSR is missing characters when it was pasted into this window.
Things to check:
1. That the key size is between 512 and 8192 bits.
2. The country code is correct
3. The illegal characters in the CSR example (%&?$) and other such
illegal characters
4. There are 5 dashes '-' at the start and finish of the BEGIN and END
lines

If you get the error shown in Figure 1, this means that a certificate
request has already been processed for this domain and you will need to
contact the account holder, or if you are account holder contact support@comodogroup.com
or passwordreminder@comodogroup.com to get your login details. Please
note that this request must come from the administrative email address
on the account.
To request a certificate for a CSR that gives this error you will need
to log into your account as detailed in
Figure 2.
My certificate says it has a nonvalid digital signature, what can cause this?
- The intermediate Comodo certificate has not been installed, you must use the one that came with the site certificate
- The wrong intermediate Comodo certificate has been installed, you must the one that came with the site certificate
