Iot Edge device module connection refused "HTTPConnectionPool , Errno 111 Connection refused "

Question

No response from classification service
HTTPConnectionPool(host='testclassifier', port=80): Max retries exceeded with url: /image (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7f7a7588d0>: Failed to establish a new connection: [Errno 111] Connection refused'))

Connectivity checks

√ host can connect to and perform TLS handshake with IoT Hub AMQP port
√ host can connect to and perform TLS handshake with IoT Hub HTTPS port
√ host can connect to and perform TLS handshake with IoT Hub MQTT port
√ container on the default network can connect to IoT Hub AMQP port
√ container on the default network can connect to IoT Hub HTTPS port
√ container on the default network can connect to IoT Hub MQTT port
√ container on the IoT Edge module network can connect to IoT Hub AMQP port
√ container on the IoT Edge module network can connect to IoT Hub HTTPS port
√ container on the IoT Edge module network can connect to IoT Hub MQTT port
√ Edge Hub can bind to ports on host

No errors are showing up when I do iotedge check

The ports which are listening on the IoT edge jetson nano

How do I resolve this error?

Hello @Amit V ,

which module do you want to deploy? Is this module publicly available? Is there a GitHub repo to examine?

From the logging, it seems a classification service is called at HTTP address "/image".

This looks like a relative path, therefore it cannot be reached, causing the error message.

It probably should have been an absolute path. Perhaps you are missing some configuration?
