“SSL Failed: WordPress reports no SSL support” this error message may show up when you enter the dashboard of Jetpack. It let users quite hard to understand what happened right now…
Fortunately, If you just use CentOS or Fedora as your server’s operating system, then I congrats that you find the right post for dealing with this issue in wordpress.
The reason should be that your SELinux blocked the connection from your server’s apache to Jetpack.
Therefore, we can make some simple adjustments to fix this problem.
This setting(httpd_can_network_connect) controls the apache of your server connects to the outside, but I think this authority is a little overhead.
$ sudo setsebool -P httpd_can_network_connect on
In view of this, if you have any other ideas to fix this problem, please leave a comment to let me know.
