Hi everyone,

Sometime since late yesterday afternoon I have lost the ability to connect to my DirectAdmin Control Panel and am wondering if anyone has any ideas what might be happening.

If I attempt to connect using Firefox 33 I am told the following...

Problem loading page. Secure Connection Failed. An error occurred during a connection to <ourserver>:2222. Cannot communicate securely with peer: no common encryption algorithm(s). (Error code: ssl_error_no_cypher_overlap). The page you are trying to view cannot be shown because the authenticity of the received data could not be verified. Please contact the website owners to inform them of this problem.

Safari tells me...

Safari can't open the page "https://<ourserver>:2222 because Safari can't establish a secure connection to the server <ourserver>".

Everything was working fine yesterday so I am at a loss as to what might have happened. This is a huge problem for me so if anyone can shed any light on the subject I really would appreciate it.

Thank you.

Roark
 
It looks like this had to do with some security updates that were installed last night (from http://help.directadmin.com/item.php?id=571).

Step 5 in the document has to do with DirectAdmin itself, it turns out that our DirectAdmin binaries were new enough that we needed the following line in directadmin.conf...
Code:
ssl_sipher=SSLv3
however, the line that was placed there was...
Code:
ssl_cipher=ALL:!ADH:RC4+RSA:+HIGH:+MEDIUM:-LOW:-SSLv2:-SSLv3:-EXP
Replacing the line and typing "/etc/init.d/directadmin restart" has seemed to fix the problem
 
I had same problem after updating the cipher list for DA, but per link above I tried the newer (safer) version below and that solved it, too.

Code:
ssl_cipher=HIGH:!aNULL:!MD5
