Description
Recently Go was updated to check the Host header more carefully.
Docker was updated to fix this by setting the Host header correctly in the client: moby/moby#45942
This fix has not yet made it into buildx. Even if buildx itself is updated, the buildkit container that it uses is the older version.
If the Docker daemon has been built with go 1.20.6, "docker build ." with a very simple dockerfile fails with ERROR: http: invalid Host header
I suggest backporting the fix for this (in the docker client) to buildx and releasing an updated buildkit docker image.
Expected behaviour
docker build . should work correctly with a Docker daemon built with go1.20.6 or newer.
Actual behaviour
The build fails with ERROR: http: invalid Host header
