Can't enter app container, still working though

Installation
1

So was attempting to ./launcher enter app on our production box to check an nginx config setting and getting the following error:

$ ./launcher enter app
/usr/bin/docker: Error response from daemon: connection error: desc = "transport: dial unix /var/run/docker/containerd/docker-containerd.sock: connect: connection refused".
ERRO[0002] error waiting for container: context canceled
Your Docker installation is not working correctly

Everything looks to be running fine on the box but for this…

And for more info, here’s my current version / status:

When I go to /admin/docker I do have an upgrade I could pull in but I don’t want to do that and bring down the whole site since this looks to be having issues at the moment - and a launcher rebuild will take things down for about ~10min

Anyone have any idea here? Worst case I can do a launcher rebuild tonight at low levels of activity…

Did you try restarting the docker service?

is that going to bounce the container? and would I just do a docker restart?

Edit: I would just do sudo systemctl restart docker correct @Falco?

Went ahead and restarted docker - took the chance and it worked. Thanks @Falco
