Some older games like Bloons TD 1 don’t route traffic through the system proxy at all, so Fiddler won’t see anything. They often use direct sockets, embedded runtimes, or no external network calls during launch. You can try running Fiddler as admin and enabling “Capture traffic from non-browser apps,” but even then it may simply not generate capturable HTTP/HTTPS traffic.

Hello Radajsa,
From what I can gather, the game seems to be using a Flash player in many of the locations where it is published. The Flash player should comply with the system proxy settings, but it is unclear how or what HTTPS requests are managed behind the scenes, as the source code is not available, and no information has been provided regarding the capturing endpoint.

It sounds like you're having trouble capturing traffic from Bloons TD 1 with Fiddler Everywhere. Here are a few things you might want to check:
Proxy Settings: Ensure that Fiddler is set as your system's proxy. Sometimes, games may bypass the default proxy settings.
HTTPS Decryption: Ensure that HTTPS decryption is enabled in Fiddler, as many games utilize HTTPS for communication.
Game Launching: Try launching the game after starting Fiddler. Some applications may not send traffic until they are opened while the proxy is active.
Firewall/Antivirus: Verify that your firewall or antivirus is not blocking Fiddler from capturing traffic.
Hopefully, one of these solutions helps you capture the traffic successfully!
