Can't pull images insecurely from private registry

General
1

I set up a local registry for testing purposes on a Linux PC running Ubuntu 18.04:

$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 18.04.3 LTS
Release:        18.04
Codename:       bionic

The registry is up and running but I can’t pull the images from another host insecurely, although /etc/docker/daemon.json looks like this:

$ cat /etc/docker/daemon.json 
{
    "insecure-registries" : ["192.168.0.145:5000"]
}

From the other host I can list the repositories of the registry:

root@sbcx:~# curl -X GET http://192.168.0.145:5000/v2/_catalog
{"repositories":["camera-capture-opencv","image-classifier-service"]}

When I try to pull an image, I get this error, however:

# docker pull 192.168.0.145:5000/image-classifier-service:1.1.91-arm32v7
Error response from daemon: Get https://192.168.0.145:5000/v2/: http: server gave HTTP response to HTTPS client
