"The certificate to verify the is not trusted in all web browsers. You may need to install an Intermediate/chain certificate to link it to a trusted root certificate" Test: openssl s_client -connect some.domain.com:443 Result: from anywhere verify error:num=20:unable to get local issuer certificate verify error:num=27:certificate not trusted verify error:num=21:unable to verify the first certificate from localhost (some.domain.com) Verify return code: 0 (ok) --- I can't figure out what is going on. If I have OK from localhost so configuration must be OK. So WHY everybody else can't see full chain?!? 443 works so it's not firewall. What I'm missing?

2010 · 2:53 am ↓ Jump to Comments GoDaddy SSL Certificates and Comodo (InstantSSL.com) Cannot VerifyIdentity when the full certificate chain bundle is not properly installed in your server some certificates appear to be INVALID and report errors like "Verify return code: 21 (unable to verify the first certificate)" The PROBLEM ----------------------------------------------------- The problem turns out to be that the server isn’t configured to provide the full issuing certificate chain all the way back to the root SSL certificate. An intermediate certificate must be installed in your server. Failure to install "the intermediate certificate" creates problems in both web browsers and command line ssl programs that do not already contain that intermediate certificate There are simple fixes for both: * NGINX * APACHE SERVERS Get the Certificate Bundle - GoDaddy ----------------------------------------------------- wget https://certs.godaddy.com/repository/gd_bundle.crt -O gd_bundle.crt Get the Certificate Bundle - InstantSSL ----------------------------------------------------- Commodo WARNS - YOU NEED AN UPDATED CERTIFICATE BUNDLE TO USE THEIR CERTIFICATES Apache users should use the bundle file on the support page instead of the Comodo and GTE certificate: If you do not install the bundle file you will receive not trusted messages when you go to the secure area of your web site. you can get a list of server bundles to choose from here ………………………………………………………………… https://support.comodo.com/index.php?_m=downloads&_a=view&parentcategoryid=1&pcid=0&nav=0 ………………………………………………………………… The Solution On NGINX ----------------------------------------------------- you just need to append the cert bundle onto your existing cert: $ cd /etc/ssl/certs/ /etc/ssl/certs$ wget https://certs.godaddy.com/repository/gd_bundle.crt /etc/ssl/certs$ cat gd_bundle.crt >> myssl.crt http://wiki.nginx.org/NginxHttpSslModule The Solution On Apache ----------------------------------------------------- SSLEngine On SSLCertificateFile /etc/httpd/ssl/*.serverdensity.c
