Socket Proxy + HA issue
I am running HA on docker, and have socket proxy as well, below is my compose for both:
socket:
container_name: socketproxy
restart: $ALWAYS_ON_POLICY
environment:
PUID: $PUID
PGID: $PGID

I did test the socket by running docker -H tcp://192.168.1.10:2375 ps on the host machine, and got the full detailed list of all containers I am running on the machine
And I have configured monitor_docker in HA as following:
monitor_docker:
- name: Docker
url: tcp://192.168.1.10:2375 #tcp://172.18.0.199:2375
monitored_conditions:
- version
- containers_total
- containers_running
- containers_paused
- containers_stopped
- status
containers:
- homeassistant
When I boot HA, in the logs, I keep getting the below (this comes out for every single container I have, even if i did not include in the configuration to be monitored):

I'm running Monitor Docker against the docker-socket-proxy running alongside the actual HA, in the same Docker on Synology NAS. The reason why I'm using docker-socket-proxy is that it's not possible to mount /var/run/docker.sock in Synology Docker GUI. When installed and configured, all worked fine. Now checking the container statuses in HA, and HA logs, I can see the same errors as reported above:

The dockerproxy container log doesn't show anything unusual, only lots of usual monitoring activities, such as: 172.17.0.1:48954 [02/Nov/2022:08:45:49.715] dockerfrontend dockerbackend/dockersocket 0/0/0/1048/1048 200 2240 - - ---- 3/3/1/1/0 0/0 "GET /v1.41/containers/518a8ff77ec9695cd12831726343178d07843dbfb988e615fedfdd59fa80d2be/stats?stream=0 HTTP/1.1"
The docker entities in HA seem to recover every time after a few minutes. Some monitored conditions seem to be affected more affected than others:
The only three monitored conditions which are not affected by this are version, containers_running, containers_total. All conditions recover to normal state after some time, without any intervention: 2022-11-02 09:22:06.583 INFO (MainThread) [custom_components.monitor_docker.sensor] [Docker] appdeamon: Initializing sensor with parameter: Health

Did you find a solution?
From my HA vm to Synology dockers this docker is working. But when I run this docker on my unraid server, I have the same issues as you.
