I'm using WHM 56 build 9. When I go Account Information -> List Accounts and click on an account's cPanel link, cPanel opens just fine. When I'm through with that account and click the Dashboard link, then use the drop-down to switch accounts, I get a "Secure Connection Failed" message with Firefox 46.0.
If I follow the same steps in Chromium, it works just fine, which makes me think the problem is with Firefox and not WHM, but unfortunately this problem started happening the same day WHM upgraded to v. 56 and Firefox upgraded to 46.0, so I'm not sure. I can't tell if there's actually an issue with WHM and Chromium is just being more lax with the secure connection, or if the problem is with Firefox.
I found this article about the error, which suggests the TLS version is out-of-date, but I'm having a hard time believing that's the case.
Does anyone have any idea how I can troubleshoot this and resolve it?
