git-tfs returns "(401) unauthorized" error when cloning a repository - git-tfs

Question

I used git-tfs to work with a TFVC repository. I started working on other project and the project's code is hosted on a different server.
Now I get errors when I try to clone the repository.
git tfs clone http://tfs-server:8080/tfs $/CompanyName/Dev
It prompts me to enter the credentials twice. Then it shows an error.
TF30063: You are not authorized to access http://tfs-server:8080/tfs.
The remote server returned an error: (401) Unauthorized.
I've double checked it is a correct url. I can connect with Visual Studio and with a browser.
I've double checked it is a correct password and username. I can log in with this credentials in a browser.
I am able to clone the code from a different server on my machine.
The server is Visual Studio Team Foundation Server 2013. My git-tfs version is
git-tfs version 0.21.0.0 (TFS client library 12.0.0.0 (MS)) (64-bit)
I've found a few questions with a similar error and tried the answers. So these are things I tried to do:
Logging off from this server in Visual Studio's browser;
Cleaning Internet Explorer cache
Deleting C:\Users\UserName\AppData\Local\Microsoft\Team Foundation\5.0\Cache folder;
Adding tfs server to local intranet security zone in Internet Explorer.
This is the debug output:
git tfs clone http://tfs-server:8080/tfs $/CompanyName/Dev --debug
Command run:git tfs clone http://tfs-server:8080/tfs $/CompanyName/Dev --debug
No authors file used.
git-tfs version 0.21.0.0 (TFS client library 12.0.0.0 (MS)) (64-bit)

What can I do to get my git-tfs flow back?

Answer 1

I've added collection name to the server's url and it worked.
The correct command was:
git tfs clone http://tfs-server:8080/tfs/collectionName $/CompanyName/Dev
Although the command in the question worked for the previous server.
