Git clone from remote repo hangs after Compressing Objects 100% done

Question

I work in Windows 7, 64-bit.

I want to check out source code from a private git repo which I am connected to by OpenVPN.

I connected to a private server via OpenVPN for Windows. The connection is established and works fine, I can ping the server and connect via SSH to it.

Next, I want to clone the git repository via

 git clone http://username:pw@url/folder

Bash shows immediately

Cloning into "projektname"
remote: Counting Objects: 6772, done
remote: Compressing Objects: 100% (6389/6389),done
_

and then hangs, no error, no clue what happens, I can cut the VPN connection to get a response from git or press Ctrl+C but nothing else.

git created a folder projektname but it is empty except for the .git folder.

I looked through forum posts for several hours, but haven't found a similar post with the same problem. I tried to get more information on git with

 GIT_CURL_VERBOSE=1 GIT_TRACE=1 git clone ....

but didn't find anything suspicious. I am thankful for any ideas about what else I can try or where I have to look into. I tried several different git clients (cygwin, Tortoise, git bash, git gui).

Answer 1

Here is the answer (So users will know how to resolve it if they need to).
The answer was posted by the owner in one of the above comments.

I found the solution... something with my router setup is wrong.
I can check out from another network.
I have no clue what could be wrong with my router , every other VPN connections just works fine.

So the problem was with the router and has nothing to do with git.
