HAProxy

When I run the image, in the logs I get the below:
Can't open server state file '/var/lib/haproxy/server-state': No such file or directory

I checked the container and did not find that folder as well

/ # ls /var/lib/
apk     misc    udhcpd

Not sure if this has a direct impact on portainer not working using the socket-proxy, as well as the HomeAssistant container showing that the TCP is disconnected

DockerError(900, 'Cannot connect to Docker Engine via tcp://172.18.0.199:2375 [Server disconnected]')

my compose for the socket / portianer / homeassistant are as following:

Start by reproducing the HAProxy log message with the published image and the supplied socket-proxy, Portainer, and Home Assistant compose settings. Trace whether the missing server-state path is related to the Docker Engine disconnection, and document a confirmed cause and configuration change or explain why the warning is unrelated.
