We're having issues accessing the staging section of our WordPress website. In all browsers we get some variant of "Secure Connection Failed". In Firefox specifically I get error code: SSL_ERROR_NO_CYPHER_OVERLAP.
The regular (non-staging) site works fine (in https) but not the staging site in either http or https. sFTP works normally, and non-PHP files seem to be accessible through http also. (i.e. http://example/robots.txt would be accessible)
Interestingly if I go to phpMyAdmin and edit "siteurl" and "home" under wp_options to change our URL from https to http then our site will work under just http, this obviously is not ideal since we want to have a secure site.
Anyway hopefully this makes sense. Any help would be greatly appreciated...
