Did you guys set anonymous login to 'true' on KepEx ?

Hi, @fwaznad, @jakem68, @aniketfidelit

I am glad to inform you that we have released new version of the Gateway based on Python. This is a major rewrite and improvement from Java version. Main benefits:

• Less footprint and memory impact
• Easier to extend and customize
• Improved functionality.

You can try to use the new gateway for connection to the OPC-UA server.

Subject: Connection Issue from PLC to KEPServerEX with Azure IoT Hub

Hello,

I'm reaching out to you because I'm currently experiencing a connection issue between my PLC, KEPServerEX, and Azure IoT Hub. Here's a summary of the situation:

Environment Configuration:

I have a PLC that I want to connect to KEPServerEX to retrieve data. I have configured KEPServerEX to use the MQTT agent to transmit data to Azure IoT Hub. Issue Encountered:

When attempting to establish the connection between KEPServerEX and Azure IoT Hub, I encounter an error stating "MQTT agent 'AZUREIOTHUB' failed to connect - reason: 'connect timed out'".I am seeking your assistance in resolving this issue. If you have any additional advice, specific checks to perform, or recommendations for resolving this connection error, I would greatly appreciate your guidance.

Thank you very much for your help.

Best regards, ARMAILI HOUDA
