Nuget connection attempt failed "Unable to load the service index for source"

While trying to connect to Nuget, I'm getting the error below, and then I am unable to connect:

[nuget.org] Unable to load the service index for source
https://api.nuget.org/v3/index.json.
An error occurred while sending the request.
Unable to connect to the remote server
A connection attempt failed because the connected party did not properly respond after a period of time, or established connection
failed because connected host has failed to respond 68.232.34.200:443

I am able to access https://api.nuget.org/v3/index.json on my browser.

Solution

  • You need to add proxy settings into Nuget.Config file. Refer to this link for details: Nuget Config Section & Nuget Proxy Settings.
