Package manager error

I just downloaded unity but whenever i make or open a project it keeps saying
Unity Package Manager error
Couldnt not establish a connection with the unity package manager local server proscess .
this is mostly likely due to a proxy or a firewall configuration make sure the proscess
[C:\Program Files\Unity\Editor\Data\Resources\PackageManager\Server/Package manager.exe]
is reachable via HTTP on the IP adress 127.0.0.1.
WHAT DO I DO?
heres a picture of the error

@Scalyfox Make sure your antivirus or firewall isn’t stopping anything.

Adding the loopback address (127.0.0.1) to the proxy ecemption list in the internet properties resolved this for me.
