The culprit in the push is that the Docker payload/content is being sent with a PUT request similar to the docker client < 1.8 versions. Modern docker client version, actually use the PATCH method for BLOB uploads
Steps to reproduce:
ctr images tag 192.168.56.1:8080/docker/alpine:latest 192.168.56.1:8080/docker/alpine:1.1 192.168.56.1:8080/docker/alpine:1.1 ctr images push 192.168.56.1:8080/docker/alpine:latest 192.168.56.1:8080/docker/alpine:1.1 index-sha256:c19173c5ada610a5989151111163d28a67368362762534d8a8121ce95cf2bd5a: waiting |--------------------------------------| elapsed: 0.1 s total: 0.0 B (0.0 B/s) ctr: content digest sha256:29a82d50bdb8dd7814009852c1773fb9bb300d2f655bd1cd9e764e7bb1412be3: not found
Capturing the HTTP traffic with wireshark shows that apparently the ctr client fails on on the below set of requests and responses (scroll down to see the last response which actually fails the client):
