In most of the places, this issue is coming in salesforce due to Domain provider server firewall only. Ask your domain Provider to provide access to load this page.
Get all the links from Chrome>Right click>Inspect>Console.
Open the console and run the component or any page which is throwing an error. Then you will get an link which needs to be shared with your domain service provider.
