Unable to get local issuer certificate within Package Manager?

Question

In Unity 2018.3 , I can no longer open a new project that requires items from the Package Manager, nor can I install a large portion of objects in the Package Manager.

I get this error on project startup...

One or more packages could not be added to the local file system: com.unity.render-pipelines.high-definition: unable to get local issuer certificate

I get this error whenever I try to install something from the package manager...

Cannot perform upm operation: unable to get local issuer certificate [NotFound] UnityEditor.EditorApplication:Internal_CallUpdateFunctions()
