Haskell stack connection timeout

I have installed stack on WSL Ubuntu using WSL2 on Windows 10. The installation completed successfully, but when I test stack with 

stack path --local-bin

I get the following error message:

ConnectionTimeout

I have seen some other posts about issues like this one, but none that are resolved, and they are older. Also, I am not on a proxy, this is my personal computer, and I turned the firewall completely off. That said, when I attempt this over a vpn connection I get a different error. Could it be an ssl/https issue since WSL2 is technically a different IP address from Windows, and so the connection is being blocked on the amazon side?

For the record when attempting the command on a VPN, the error I get is

Update

Reverting to WSL-1 "solves" the problem, so the issue is something specific to WSL-2. I replicated the problem with a fresh install of Windows on a separate machine, but haven't found a way around the issue yet.

I can confirm that this problem no longer exists using stack 3.1.1. So, upgrade stack, and you'll be good to go.

I have wls2 ubuntu 20.02 installed on my pc
fixed this problem with changing the contents of /etc/resolv.conf

cd /etc
sudo *your favorite editor* resolv.conf

added Google DNS servers as

nameserver 8.8.8.8
nameserver 8.8.4.4

this fixed stack not working for me.
