Pushing to docker hub - one layer stucks

Hello everybody,

I try to push a image to docker hub. Unfortunatelly, the push stucks at a certain layer. I already set “max-concurrent-uploads”: 1, but this is not working, too. Any suggestions?

Thanks a lot.

Have you tried it later again? Is it waiting every time you try? When layers exist Docker does not need to send much data to the registry. Non-existing layers need a stable network. If you are on an unstable network like wifi, it can slow the uploading down or even stop it. Other known issue is that Docker Desktop has more problem with networking than Docker CE on Linux. When I used Docker in an UTM virtual machine that was unstable too probably because I did not configure UTM properly. I tried later and it worked. If it never works, then It can be a firewall issue too.

Yea, always the same result. But I figured out that this is related to my firewall. Don’t know why just certain parts are not working, but deactivating the firewall was doing the trick. Thanks for your help.
