The setting for Message Server changed from V4 to V5.
For example, assuming that your Server Computer Name is either “ServerName” or has an IP address of “192.168.1.50” and that the Message Server Port is configure to be 9000 …
V4 clients should be configured to connect to Message Server Port of 9000 and the Message Server Name like of the following
ServerName
192.168.1.50
V5 clients should be configured to connect to Message Server Port of 9000 and the Message Server Name like of the following
http://ServerName
http://192.168.1.50
Also, using the Message Server Service Tool, you should ensure that the Port setting includes a + symbol, such as:
9000+
NOTE: do not use the + symbol in the Client configurations (including the Server Terminal) for the Message Server Port. The + symbol should only be used in the Service Tool settings.
Besides all of that, I would be surprised if V4 and V5 could even talk to eachother in the first place. But do note: DB connectivity has nothing to do with the Message Server, nor the Connected status. The Message Server is for sending notifications to other Clients to perform updates to their displays only.
