Answer 1

I was not using any third party firewalls when running into this error. I was convinced it was a Windows Firewall issue, though disabling Windows Firewall did not work for me. I finally found this blog post after much research: Docker on windows 10 error: A firewall is blocking file Sharing ...

It ended up NOT having to do with the built in Windows Firewall.

The Fix

1. Uncheck File and Printer Sharing for Microsoft Networks from the vEthernet (DockerNAT) network adapter (you can find the connection in the Windows Network and Sharing Center).
2. Recheck it and make sure it is enabled.

I had same issue with F-secure, DeepGuard was blocking the Docker service. My solution was:

Open F-secure client and click "Tasks"

Choose "Allow a program to start"

Choose from list "com.docker.service" and press "Remove"

After that restart Docker client and try to apply for file share.

Everything everyone posted DID NOT WORK for me.

THIS DID.

I installed the EDGE release. I then went to WINDOWS DEFENDER and disabled the firewall for DOCKER NAT. (not my actual ethernet adapter, just the docker nat)

ugh. really hopes that helps some of you!
