 * Since yesterday I got this connection error, but before all was OK, How could
   I fix this?
 * “A network problem or firewall is blocking all connections from your web server
   to WangGuard.com. WangGuard cannot work correctly until this is fixed.”

 * Hi [@passegua](https://wordpress.org/support/users/passegua/),
 * WangGuard 1.6 is using port 443 (SSL) by default. If you cannot open that port,
   go to WangGuard Configuration And look if “Connect to WangGuard API using SSL/
   TLS”. is unmarked and Save Options.
 * Then, try if your website is connecting to WangGuard again.
 * kind regards

 * Hi again [@passegua](https://wordpress.org/support/users/passegua/),
 * Please, update to 1.6.1 and if you have connectivity problems, mark disable secure
   connection to WangGuard API in WangGuard configuration.
 * Kind regards

 * Have you considered an option to leave SSL enabled but to not verify the certificate?
   I am running CentOS 5 and have found that was the fix for some other issues I
   was having with other plugins (I was able to use a filter since it was using 
   WP_Http() – [http://justinsilver.com/technology/wordpress/admin-columns-pro-ssl-upgrade-fix/](http://justinsilver.com/technology/wordpress/admin-columns-pro-ssl-upgrade-fix/)).
 * Thanks!

 * Hi [@doublesharp](https://wordpress.org/support/users/doublesharp/), I can take
   a look, but i don’t like the idea, because if WangGuard plugin don’t verify the
   certificate, many people can think that there is something wrong with the certificate
   or the plugin. And there is a very big hole without verification, if someone 
   hack your server and change the hosts (for example), the certificate will works,
   so you can be sending the emails for verification to a hackers instead to us.
 * Read this post, maybe is the solution for your problem.

 * Awesome, thanks for that link… I tried to figure this out forever and it never
   occurred to me that curl wasn’t picking up the update cacerts.pem. Once I added
   it to my php.ini file SSL is working as expected, thanks again!

 * Actually, I take that back. Even with the updated cacerts.pem specified in php.
   ini I still cannot connect unless I disable SSL entirely. I have root access 
   to the server running CentOS 5.11 if you have any other suggestions. It would
   be great to not have to disable SSL entirely, but if I don’t I can’t connect 
   to the WangGuard API IP address.

 * Because the latest SSL bugs, I’ve disabled some SSL protocols, maybe this is 
   the problem.
 * I will update you.

 * Yeah… I suspect it is trying to fall back to SSLv3. The real solution is for 
   me to upgrade to CentOS 6. Now all I have to do is find some free time 🙂
