I haven’t found this question in any other category, and I think this the apropriate one to host it.
I’ve installed two Openfire servers on two different machines, in two different networks (one is inside a LAN an the other on a DMZ / public network. They see each other, but I think this does not count for my question).
I only am able to connect to both of these servers by using the Spark IM client. I’ve tried Pandion (which is currently used in our company alongside a Wildfire 3.1.1 server), Psi, Exodus, Coccinella and a few others, without any chance of success.
The Openfire servers were installed in version 3.3.2. At that time, Exodus and Coccinella were still able to connect.
They’re now updated to versions 3.4.1 and lately 3.4.3 (both), and I can only connect using Spark.
The servers use a SSL self-signed certificate, but so does the old Wildfire (who does accept connections from any of the above mentioned clients).
Does anyone know of any reason why the other clients would not connect?
Thanks in advance.
