Whenever I try to install an extension on Magento via SSH or via Magento Connect (/downloader) the following error happens:

error:14077410:SSL routines:SSL23_GET_SERVER_HELLO:sslv3 alert handshake failure!

This happens on all versions from 1.5 -

This happens with any extension.

  • So do they plan on fixing it server-side anytime soon? I've seen this affecting many Magento Connect installs.

  • They can't fix it server side because that would require them to turn SSLv3 back on which is a security risk.

If you have received a version of the:

error: 14077410:SSL routines:SSL23_GET_SERVER_HELLO:sslv3 alert handshake failure! error while trying to install a Magento Connect extension, it's because Magento turned off SSLv# on Magento Connect, but curl is still trying to connect with SSLv3. Here is a solution we came up with a few days ago - I wrote about it on our blog: https://www.dwdonline.com/blog/fix-magento-error14077410ssl-routinesssl23_get_server_hellosslv3-alert-handshake-failure.html

  • Shouldn't Magento fix this server-side somehow? They changed the way a service functions (obviously with consideration to security) but by doing so they broke their service for many users. I've experienced it a few times now with clients on production environment.

    It's not possible. The only way for them to fix this on their side is 1, turn SSLv3 back on (bad choice as it's a major security risk), or 2, they could (and probably will) release a patch - much like mine, or 3, they will fix it in 1.9.1.x. Until then the only way it to patch it as I've mentioned. They will probably release a patch (much like mine) I'm supposing. In fact, I've been in contact about that. Commented Feb 24, 2015 at 1:43
