Hi,
http://ipv4.fiddler:8888/ is the Fiddler Classic's echo service and it will work on your machine only when you have the Fiddler Classic running and using the default port (8888). So, just run Fiddler Classic, ensure you are using port 8888 (in the Fidlder options -> Connections) and open the http://ipv4.fiddler:8888/ - it should work.

The error indicates that, for some reason, your remote device is not "seeing" the Fiddler proxy. While there are many possible reasons why that happens, the most common are:
- The proxy is not properly configured on the target device.
- The Fiddler host Is not in the same local network as the target device.
- A security tool (like a firewall, antivirus, zero-trus tool, administrative policies, etc.) limits network access.
The term "ipv4.fiddler" is an internal alias used by Fiddler to refer to the loopback address. When Fiddler is opened at ipv4.fiddler:8888, it creates a local server that runs on 127.0.0.1:8888. If your remote device is unable to access the Fiddler page while using this alias, it likely means that either the remote device cannot reach the Fiddler host or the Fiddler application is not running. The ipv4.fiddler alias is only accessible when Fiddler is active, and both devices must be on the same network and properly connected.
