git ls-remote succeeds while go get fails

git ls-remote command succeeds for a repo as shown below.

git ls-remote https://internal.net/dir1/dir2/dir3/repo
warning: redirecting to https://internal.net/dir1/dir2/dir3/repo.git/
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx	HEAD
yyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy	refs/heads/master

However, when go get is used the cmd fails with repository not found. The error output tries to find .git at 1 directory above the repository structure.

go get internal.net/dir1/dir2/dir3/repo@master
go: internal.net/dir1/dir2/dir3/repo@master: invalid version: git ls-remote -q origin in /Users/{{UserId}}/go/pkg/mod/cache/vcs/xyz...: exit status 128:
	remote: The project you were looking for could not be found or you don't have permission to view it.
	fatal: repository 'https://internal.net/dir1/dir2.git/' not found

My goprivate is
GOPRIVATE=internal.net

What am I missing here for the go get to succeed?

Add a VCS suffix to the private module path to mark the repository root prefix:

go get internal.net/dir1/dir2/dir3/repo.git@master

See Direct access to private modules:

> An internal HTTP server may still be needed to resolve module paths to repository URLs. For example, when the go command downloads the module corp.example.com/mod, it will send a GET request to https://corp.example.com/mod?go-get=1, and it will look for the repository URL in the response. To avoid this requirement, ensure that each private module path has a VCS suffix (like .git) marking the repository root prefix. For example, when the go command downloads the module corp.example.com/repo.git/mod, it will clone the Git repository at https://corp.example.com/repo.git or ssh://corp.example.com/repo.git without needing to make additional requests.

Please note that the VCS suffix is a part of the module path, so it should be included in all the places where a module path is used. Including:

1. the module directive

   module internal.net/dir1/dir2/dir3/repo.git
   

2. the require directive

   require internal.net/dir1/dir2/dir3/repo.git v0.0.1
   

3. the import declaration

   import "internal.net/dir1/dir2/dir3/repo.git/pkg/util"
   

4. and more.
