Can't use FQDN of host when pushing images to remote registry (Unsecure)

[Annihil8ted]

Hello All,

I'm using Ubuntu 14.04 LTS.

Client:
Version: 18.02.0-ce
API version: 1.36
Go version: go1.9.3

Engine:
Version: 18.02.0-ce
API version: 1.36 (minimum version 1.12)
Go version: go1.9.3
Git commit: fc4de44
Built: Wed Feb 7 21:15:21 2018
OS/Arch: linux/amd64
Experimental: false

When running the following on host machine:
docker run -d -p 5000:5000 --restart=always --name registry registry:2

From a remote machine, I cannot push using the host FQDN. I must tag and push using the ip.

If I push using FQDN, it continually attempts to retry until a 503 is hit. I've done the installation once over already and have produced the same errors. I also tried via enabling self-signed HTTPS and I get the same issue.

@Annihil8ted to be able to provide insight in this, we need your configuration (redacted), the exact command line you have been using, and both the registry logs and docker daemon logs (from where you are trying to pull).
