BlogEngine.Core.Packaging.Load error

[Jimbo101022]

I am getting this error when I click on any save button in Admin portal:

BlogEngine.Core.Packaging.Load: Could not connect to the feed specified at 'https://devinschumacher.com/'. Please verify that the package source (located in the Package Manager Settings) is valid and ensure your network connectivity.

httpRuntime targetFramework="4.8"

Any help would be appreciated. Thanks.
