Http timeout in edgeAgent deployed in device

Question

At times, I see edgeAgent module running in our device often timing out when pulling images for deployment and after restarting the module it works. Any suggestion?

Hello @Jeffrey K ,

this is a (moderated) community forum with volunteers answering questions.

It seems you found an issue with Azure IoT Edge logic.

This logic is open-sourced here and the product team is monitoring the repo.

Please add an issue there and reference the issue here for traceability.
