goproxy: 404 not found

• docker build . -t goproxy
• docker run -d -p 8081:8081 goproxy
• Then I wrote a script to test :

#!/usr/bin/env bash

export GO111MODULE=on
export GOPROXY='http://127.0.0.1:8081'
export GOPATH=`pwd`

go get -v golang.org/x/crypto

• Script output:

• docker logs output:

• When I replace http://127.0.0.1:8081 to https://goproxy.io it is no problem.

 #!/usr/bin/env bash

export GO111MODULE=on
export GOPROXY='http://goproxy.io'
export GOPATH=`pwd`

go get -v golang.org/x/crypto
