Using iOS 13.4.1

Using Catalina 10.15.4

Using Fiddler for Mac

I have followed this https://www.telerik.com/blogs/how-to-capture-ios-traffic-with-fiddler blog post for configuration. 

But when I try to go to the http://ip4v.fiddler:8888 I get the below error

[Fiddler] DNS Lookup for "ip4v.fiddler" failed. System.Net.SocketExceptionFactory+ExtendedSocketException Device not configured
