Push a NuGet package that already exists

Hello,

I am trying to push a package with the same version as one in the server, looking at this link (http://docs.octopusdeploy.com/display/OD/Push+a+NuGet+package+that+already+exists) I added the ?replace=true argument to the url but still get error 400. bad response.

the request will work if the package doesn’t exist in the library already and fail at the second attempt.

Thank you
