Are there any messages in the logs of either the gateway or the vision client around the time that you had a connection issue? Any recent changes to your network by IT?

no we don't changes in our network and we don't recivet any messages in the logs about this.

if we connect to the Mitsubishi software we can enter the PLC configuration.
