So I recently installed Ubuntu WSL1 in my company PC and ran this command to update my installation, It seems ping is successful but "apt-get" fails to connect and download. I need some help here to trouble shoot this

sudo apt-get update

I'm getting the following error:

Err:2 http://security.ubuntu.com/ubuntu focal-security InRelease

  Could not connect to security.ubuntu.com:80 (2001:67c:1562::18). - connect (111: Connection refused)

I tried to ping archive.ubuntu.com and it is showing me it's successful. but the apt-get update does not work ?
