I’ve got an edge-agent running on docker on a new gateway.
Connected to Losant OK 1st time.
Power cycle the gateway, Docker and the agent boots up OK, however it can no longer connect to Losant broker.
Could it perhaps be related to DNS. (Online forums searching)
Or, related to me having configured using environment variables? (Would you advise using a configuration file?)

stopping, removing the container, then re-creating, did not work.
sudo service docker restart - this did work. However is obviously not the solution

Hi @ChrisGM !
[`EAI_AGAIN`](https://www.codingdefined.com/2015/06/nodejs-error-errno-eaiagain.html) corresponds to a temporary failure in name resolution, which indicates a problem with reaching the DNS server, or the DNS server responding with an error. These are Docker / network issues outside of the Edge Agent.
Since restarting the Docker service resolved the issue, it might be that the network changed on the host system since the container started. See [this thread](https://stackoverflow.com/a/61955468) for more information and potential solutions.

Thanks, some scripting to restart docker on a delay after startup solves this issue.
