error while pulling image

Hi
I got an error when I wanted to pull an image from the docker hub. the error is an error response getting manifests: 404

I tested all of these registries :
https://index.docker.io
https://index.docker.io/v2
https://registry-1.docker.io/v2/
https://registry-1.docker.io/

but no success

my router OS version is 7.8

It is a known issue, Snowzach, a user has described a potential solution: http://forum.mikrotik.com/t/v7-8beta-testing-is-released/163742/202

I am getting the same errors when trying to pull uptime-kuma container.
[cont] error response getting manifests:404
was unable to import, container 7488cd1c-7ee6-49d0-9c36-91353e2c4131

This is my first attempt at installing containers
Network environment is built (bridge, veth interface, ip address, port, etc.
V7.18.2
most of the reports of this error were in 2023 on V7.9/7.10 so it must be something else I am not doing correctly.

I encountered exactly the same issue and the log said

[cont] unexpected response from container registry: SSL: internal error (6)

I had the same issue trying to pull a postgres image, after adding "library/" to the remote-image it worked (tested on v7.18.2 and v7.20rc2 on my RB5009)

ERROR 401
/container/add remote-image=postgres:17 interface=veth-db mounts=pgdata envlist=pg-env logging=yes start=yes

OK
/container/add remote-image=library/postgres:17 interface=veth-db mounts=pgdata envlist=pg-env logging=yes start=yes

Hope this helps
