Having trouble with Proxy server settings? Need help configuring them correctly? or What are the best

Wow, thanks for all the tips! Didn’t realize how much DNS and cache could mess with Proxy server settings.

Tried Fiddler and already see some weird timeouts. Gonna tweak the timeout values and test again.

Quick Q: Anyone know if VPNs interfere with proxy configs? Might be my next hurdle lol. Cheers!
