This looks there is no connectivity to the Docker API on 10.10.1.12 on port 2375?

[redpizza69]

I am to getting the same "Cannot connect" messages one by one for each of my containers. I am using a docker proxy (tecnativa/docker-socket-proxy) rather than docker.sock. Once a container get this error then I get no more stats for that container, so gradually over time all my containers become 'lost'.

Is it possible that due to the relative high polling of the proxy (I am polling around 20 containers) that occasionally a connection times out, but then monitor_docker doesn't try that container again?

I also get disconnect warnings when setting the scan_interval to a value lower then 30. Not sure yet if it's the proxy not able to handle the number of requests at that speed or if Home Assistant struggeles with processing them fast enough. Both HA and the proxy are on powerful hardware, so a bit strange... I'm running 34 docker containers at the moment.

This issue is resolved in v1.11?

I will close this old issue. If still persists, please open a new issue.
