Multi server - ssl connection fails

[loesberg]

On a new server install I have setup multi server to my 2 other existing Directadmin servers. The new server gives back an error when I test the connection;

www.xxx.yyy.zzz : : Unable to connect to www.xxx.yyy.zzz: Invalid argument
Unable to connect to secure socket
Some I/O error occurred. The OpenSSL error queue may contain more information on the error. If the error queue is empty (i.e. ERR_get_error() returns 0), ret can be used to find out more about the error: If ret == 0, an EOF was observed that violates the protocol. If ret == -1, the underlying BIO reported an I/O error (for socket I/O on Unix systems, consult errno for details).
openssl error queue:
empty error queue. ret=-1
errno: Bad file descriptor

The 2 other servers can successfully connect to the new server and each other.
I have searched the forum and on Google but so far have not been able to find a solution.

All servers have ssl=1 in directadmin.conf and Directadmin is available over SSL on port 2222.
Firewalls on the servers have been opened for each other and I have tested with the firewall switched off, no joy.

Any tips are most welcome.

When I switchoff SSL and try a http connection I get the following error;

185.xx.yy.zz : : Unable to connect to 185.xx.yy.zz: Invalid argument
Unable to open a socket

So the problem is not just ssl related.
Outgoing connections are allowed by the firewall.
