What is Web Code 407 and Why Does It Happen? Let’s Break It Down!

Thanks for all the replies, everyone! Super helpful. I tried clearing my cache and disabling my VPN, and it worked! Turns out my VPN was the culprit.

I’m still curious though—why would a VPN randomly trigger a 407 error? Like, it was working fine before. Is it something to do with the VPN server?

Also, I checked out Fiddler like some of you suggested, and it’s pretty cool. Gonna play around with it more. Thanks again! 🙌
