Hello @TITAN,
Just wanted to follow-up on this issue!
It's great to hear that you were able to resolve the issue by upgrading to a higher tier plan for your web app. It's possible that the issue was related to resource limitations on the free plan, or that there was a temporary outage on the Azure side.
However, if the issue occurs again, or if you experience any other issues with the web app or IoT Hub, there are a few things you can try:
- Check the Azure status page: Sometimes, Azure services experience issues that can affect your applications. You can check the Azure status page (https://status.azure.com/en-us/status) to see if there are any known issues with the service you're using.
- Check the logs: You mentioned that you enabled logging, but didn't see anything there. If the issue occurs again, be sure to check the logs for any error messages or other information that may help you diagnose the issue.
- Use a tool like Fiddler or Wireshark to capture network traffic: If the issue is related to network connectivity or communication between your IoT device and the web app, capturing network traffic can help you see what's going on and identify any issues.
- Try a different device: If you have access to another IoT device, you can try using it to send data to the IoT Hub and see if the issue persists.
- Reach out to Azure support: If you're still experiencing issues, you can reach out to Azure support for assistance. They can help you diagnose the issue and suggest possible solutions.
I hope this helps!
