I am completely new to Unity. I have just installed Unity 2018.3.14f1. I opened Unity and clicked on new project. But unfortunately some error popped up. It said - Could not establish a connection with the Unity Package Management local server process. This is most likely due to proxy or firewall configuration. Make sure the process [D:/Unity/2018.3.14f1/Editor/Data/Resources/PackageManager/Server/UnityPackagemanager.exe] is reachable via HTTP on the IP address 127.0.0.1. Please help me solve the problem. Thanks in advance!
