I just installed the latest release of docker-ce on CentOS, but I can't reach published ports from a neighboring server and can't reach the outside from the container itself.
CentOS firwalld blocks outgoing docker requests, leading to failing ingress/egress dns resolving.
In my case, disrupted Nextcloud working (since I have external primary object storage configured), as well as outgoing requests from SearX.

When I had this problem, it was a DNS problem. Traefik was trying to connect to the wrong IP address - an IP address that was on a network with no access from traefik.
Setting providers.docker.network solved my problem - but careful, you need to use the full network name as visible with docker network ls (in my case it was pi_traefik-web - for you it should be traefik_proxy).
In theory, you could also set the label traefik.docker.network=traefik_proxy to your nextcloud-app service.
This problem can be diagnosed through the traefik dashboard: look for the network ip a specific service is assigned -- does it show the 'public' network compatible ip?
I am using portainer and am unable to manage remote endpoints. I tried using the command line to connect to remote docker nodes, but got a message Cannot connect to the Docker daemon at tcp:
Awesome traefik 2.0 explanation using docker (compose)
Really good introductory video for kubernetes concepts;
breaks down with simple analogies and really quick history: pods, services, ingress, deployments, resource allocation vs dynamic resource management; rolling update; and probably 1-2 things more
