My client keeps losing connection to the server. How can I find the error?
In order to be able to work with the database without any problems, you need a perfect network connection to your server. Various sources of error can affect the connection between 4D Client and 4D Server:
Sudden workstation sleep
Unreliable network connection
Defective network cable
Defective router/switch
Defective network card
Since 4D Client and 4D Server are in constant communication, 4D Client is more sensitive to network disturbances than a web browser or an e-mail program. It is therefore possible that problems that already exist only become apparent after the database has been put into operation, although they have existed for a long time. Definitely make sure that
Your computer is connected to the network via LAN (cable) and not via WLAN . Plugging in the network cable is often not enough. You must also ensure that the computer uses the wired network with priority. Otherwise you run the risk of having plugged in the network cable but still communicating via WLAN.
hibernation is turned off. You can dim the screen in your computer's power options, but the computer should not be able to go to sleep on its own. Otherwise the connection to the server will be interrupted.
Note for users of timeSensor LEGAL Classic: How sensitive the 4D database reacts to interruptions and disruptions depends on the database version. Starting with Database 19.6, a new network protocol that is more fault-tolerant than the previous protocol will be used by default. If you have problems, you should therefore make sure that you are using build 3695 or newer. With timeSensor LEGAL 365, the new network protocol is always used.
