Hi @wint0178, when you logged in to the server, if you see this error, it was happened before login.
If it comes only one time and all other functions are working as expected, please ignore this error.

@wint0178 can you access the server on the localhost or in LAN?
Are you seeing the error on UI? Can you share the screen shot?

Thanks @wint0178 !!
I will go through the installation documentation and sync with your update.

@wint0178 Thanks for the details
I see you have an trailing space after \ ("--env TZ="Asia/Kolkata" \ "), that leads restart command not found
I have updated your timezone and removed the extra space, can you please try the following command to start the MyController server?

go to your mycontroller directory(root of mc_home and location of mycontroller.yaml) and run the following command

docker run  --detach --name mycontroller \
  --network mycontroller \
  --publish 8080:8080 \
  --publish 8443:8443 \
  --publish 9443:9443 \
  --volume $PWD/mc_home:/mc_home \
  --volume $PWD/mycontroller.yaml:/app/mycontroller.yaml \
  --env TZ="America/Chicago" \
  --restart unless-stopped \
  docker.io/mycontroller/server:2.0.0

If it doesn't comes up please run the following command, I just removed the --detach(don't run on background) and added --rm (remove the container on termination)

docker run  --rm --name mycontroller \
  --network mycontroller \
  --publish 8080:8080 \
  --publish 8443:8443 \
  --publish 9443:9443 \
  --volume $PWD/mc_home:/mc_home \
  --volume $PWD/mycontroller.yaml:/app/mycontroller.yaml \
  --env TZ="America/Chicago" \
  --restart unless-stopped \
  docker.io/mycontroller/server:2.0.0

I assume if I uninstall docker to try and update it using the code you include in the documentation, as you suggested, that I will also need to reinstall influxdb, natsio, and mqtt. Is that correct?

Yes, In the docker just removes the containers and creates from fresh.

I was just messing with your install from executable binary instructions and I got the MC server running and can pull it up at localhost:8080. When I run docker ps -a I am still getting the same three services running: mqtt, influxdb, and natsio. Is this correct?

executable is different than the docker. It will not be come under docker ps command.
It executes directly on the host system.
I would recommend to use docker version of mycontroller, for the portability and maintainability

the running server on localhost has a warning that the Metrics database is disabled. I assume this has to do with installing MC from the binary, but it feels like progress anyway.

This is because, executable which is running on outside of docker network and can not resolve the hostname used inside docker. If you replace hostname of mc_natsio, mc_influxdb to localhost on your mycontroller.yaml [1] should work. However, I would recommend to try the docker version of mycontroller.

[1] - If you apply this change, it will not work on docker version of mycontroller

@wint0178 What is the log do you see on the mycontroller container?

docker logs mycontroller

and what is the output of,

docker ps -a

This is where I get hung up, but I'm not sure if I have settings above here incorrect or if there is something wrong with the following install/run commands.

Can you please elaborate? Does the terminal hung to return?

@wint0178 on the other post, I see you were able to see the nodes. Still do you see this issue?

@wint0178 Are you using MySensors library?
Your MQTT broker should be accessible to all of your hardware gateway nodes and MyController server. MyController server is acting as MQTT client, just like another MQTT device in your network.

@wint0178 You can use letsencrypt certification setup with https_acme to your DDNS setup, https://v2.mycontroller.org/docs/installation/advanced-installation/backend-configuration/

@jkandasa I have fixed this. available in the docker container(2.1.0-devel). yet to update in executable.

@wint0178 I have not experienced this kind of issue. check the filesystem. you can find the root cause. Please let us know your findings. You can check this after your family road trip
