Stuck in Network azure-iot-edge-dev is external, skipping

Question

Runing the Build and Run Iot Edge Solution in Simulator stopped working suddenly, and the log builds the containers and stops at this message Network azure-iot-edge-dev is external, skipping Everything was working fine 5mins ago, tried rebooting, restarting docker, iotedgehubdev, but in vain. Do you know how can I get more logs and/or resolve this problem ?

Answer 1

This is a generic error that is thrown for a variety of reasons. Possible causes can be:

• Proxy blocking pulling images of edgeHub and edgeAgent
• A problem in the deployment.template.json (or debug template), e.g. missing brackets
• Ports of edgeHub that are in use
• Docker configured for Windows containers when targeting Linux or visa-versa

The Build output or IoT hub output in Visual Studio usually gives a bit more information.
