DNS unmarshal error when pulling from private repo with long url

See original GitHub issue

Actual Behavior

Recently updated to 1.1.1 hoping it’d resolve, but still having this same issue which I was also having with 1.1.0 and commented on thru issue 893

Pulling from public repos works fine, but when I try to pull from my team’s private repos over our company VPN and containing long urls, I get back cannot unmarshal DNS message below. This does not happen with Docker Desktop which uses kubernetes.docker.internal that’s mapped to my local (Windows) host in c/Windows/System32/drivers/etc/hosts.

docker pull teams-docker-dev-repo.docker.artifactory.my-company.com/base/service-img:10b2d1bb

Error response from daemon: Get "teams-docker-dev-repo.docker.artifactory.my-company.com/v2/": dial tcp: lookup teams-docker-dev-repo.docker.artifactory.my-company.com on 172.18.71.212:53: cannot unmarshal DNS message

Since my local Docker Desktop instance can pull the same private repo image down w/o issue while connected to the same VPN, I don’t think it has anything to do with the DNS issue in the Rancher Desktop context, but added that detail in case it does for any reason(s).

Steps to Reproduce

Try to pull an image from a long repo url, e.g. docker pull teams-docker-dev-repo.docker.artifactory.my-company.com/base/service-img:10b2d1bb. This same url works w/o issue on Docker Desktop, not sure what the deltas are and why it would be able to handle the same url w/o issue

Result

Expected Behavior

I should be able to pull from both public and private docker image repos with longer urls the same way I can in my Docker Desktop context

@Nino-K I have good news, I’d root caused this and worked with the Go team to ensure this was released & backported: https://github.com/golang/go/issues/51127
