Albert, The packet size was increased in 2.9 that caused 2.9 clients to fail with older servers and 2.9 servers to fail with older clients. A fix was implemented in the server in 2.9.1 that would allow older clients to connect to it, but 2.9 and newer clients will not be able to talk to older servers because they still use the larger packet size.
The reason the fix is in the server is because there are far fewer servers than clients, meaning less things to replace in order to get things working. If you update your server, your older clients should be able to connect. Hope that helps.
