I usually update these packages together so I can ensure their server supports TLS properly yum -y update ca-certificates openssl nss wget openssl libcurl This will output an error message that TLS is not support. Yes, they are definitely running without any updates. The result would be something like this 6_1.5.noarch You must be running CentOS 6.x otherwise these upgrades will not work for you and you probably running an end of life operating system. They are running CentOS 6.4 which has an older version of libraries and needs to be upgraded. My first thougth is their server hasn’t been upgraded lately, and their TLS support is not current.
