dotnet restore consistently times out on Win7x64

Steps to reproduce

Install the LKG version off of https://dotnet.github.io/getting-started/ and install. Then do the following:

mkdir new
cd new
dotnet new
dotnet restore

Expected behavior

The packages are restored and the lock file is generated.

Actual behavior

Works very slowly at first and then it starts spitting out messages like the one below. After a while, simply exists with restore not done.

Also tested on a Linux VM that is connected to the same network, same version installed from the feed, no problems, restores fast and nice.

I am seeing the same problem. It seems that in my case the traffic was routed to an incorrect network interface. I’ve disabled the VirtualBox interface (earlier I had it running with a VM in host-only network mode). There also was OpenVPN running with an active VPN connection, I closed the connection but did not disable the interface. I also disabled all other network interfaces (bluetooth and unconnected wired ethernet port).

I haven’t seen this problem with other software while the VPN and VirtualBox are active regularly on my system.

@emgarten install Win7SP1, install Virtual Box, install CLI tools. Do:

dotnet new
dotnet restore
