# SSL Upgrade Network Errors

 * I’m running WordPress with 3 sites in the multisite network. Only the main site
   is set up to use SSL. When attempting to run ‘Upgrade Network’ via the Network
   Admin I get the following error:
 * **Warning! Problem updating. Your server may not be able to connect to sites 
   running on it. Error message: error:14077410:SSL routines:SSL23_GET_SERVER_HELLO:
   sslv3 alert handshake failure**
 * At first I had some verification errors, so I’ve put the following (as a plugin)
   in my main site:
 *     ```
       add_filter('https_ssl_verify', '__return_false');
       add_filter('https_local_ssl_verify', '__return_false');
       ```
   
 * But now I can’t seem to find a way to get around the handshake failure issue.
   Please help!
 * I’m running the latest version of WordPress, including the All In One WP Security
   plugin, WP SuperCache, and CloudFlare with forced SSL on the main multisite domain.
   All sub-sites are using mapped TLDs without SSL.
 * Please help!

 * Change that to an MU plugin for all sites on the network for one.
 * For the other, what version of SSL and Secure CURL are you running on the server?
   They may be out of date.

 * Hi Mika, I’m not sure about the SSL or Secure Curl. I’m using (mt) Mediatemple(
   gs) Grid-Service. Should I reach out to them about it?

 * I contacted (mt)… Here’s what they had to say…
 * >  This isn’t an error we’ve received a large number of reports for, although
   > there is a concern I have regarding part of the message:
   > “sslv3 alert handshake failure”
   > SSLv3 is one of the protocols that was vulnerable to the recent POODLE vulnerability.
   > As a consequence, it was disabled on the Grid. Connections should be made using
   > TLS instead to ensure that they are secure. You may need to make the appropriate
   > modifications to your site, plugins, etc. to ensure that SSLv3 is not used.
   > Regarding the version of Curl running on the server, since the Grid hosting
   > service is a shared hosting platform, this software is managed by our engineers
   > and cannot be updated by the end user.
 * This doesn’t really help me. I didn’t change anything in my site since the last
   successful “network upgrade” other than enabling and enforcing SSL and setting
   up CloudFlare.
 * Still trying to figure out how to fix this.

 * BEFORE you enforced SSL, though, you see, you weren’t using it to communicate…
 * The upgrade network button is all internal, it’s not calling out to wp.org or
   anything, it’s just updating the DB.
 * Turn off All In One WP Security. It’s a stab in teh dark but it make be stuck.
