Hello,
I need for an application to connect a ctrlX as an OPC UA client to an existing Rexdroth IoT Gateway as OPC UA Server.
I tested it OPC UA connection to the IoT Gateway with UA expert and it works fine :
With following settings:
Now, when I try to connect my ctrlX OPC UA client it does not work, I have always an error : DL_COMMUNICATION_ERROR:
I searched on ctrlX user manual and alos with the question mark : (?) on the error but the description is empty :
I checked ctrlX log files and IoT gateway log files but I didn't find any information about this problem.
Here are my client OPC UA settings :
I tested from my ctrlX to ping the IoT Gateway and it works.
I checked if port 9999 is open and it is also ok.
I added (manually) on the IoT Gateway OPC UA server the certificate of my ctrlX client but it didn't improve the problem///
Where can be my mistake? Do you have any idea?
