Connection Request Failed 407: Proxy Authentication Required – How to Fix This Error?

18 Replies, 1842 Views

Hey guys,

So I keep getting this "connection request failed 407" error whenever I try to connect to a server. It says "Proxy Authentication Required," but I have no clue what that means or how to fix it.

Anyone else run into this? I’ve tried restarting my router, clearing cache, and even reinstalled the app, but no luck.

Is there a setting I’m missing or something? Or do I need to contact my ISP? Kinda frustrating ngl.

Thanks in advance for any tips!

P.S. If you’ve fixed this before, pls share how you did it. The "connection request failed 407" thing is driving me nuts lol.
Hey! I had the same "connection request failed 407" issue last week. Turns out it was a proxy server issue. If you're using a proxy, make sure the credentials are correct.

You can check your proxy settings in your browser or app settings. If you're not sure, try disabling the proxy temporarily to see if it works. If it does, you might need to reconfigure it or contact your network admin.

Also, tools like Fiddler or Charles Proxy can help debug proxy-related issues. Hope this helps!
Yo, I feel your pain with the "connection request failed 407" error. It’s usually tied to proxy authentication. If you’re on a work or school network, they might require a proxy.

Try this: Go to your network settings and look for "proxy settings." If there’s a username/password field, make sure it’s filled in correctly. If you’re not sure, ask your IT department.

If it’s a personal network, you might wanna check if your ISP is forcing a proxy. Sometimes they do that for "security reasons." Annoying, I know.
Hey there! The "connection request failed 407" error is a proxy thing. If you’re using a VPN or proxy, double-check the settings. Sometimes the app or browser doesn’t pass the credentials properly.

I’d recommend using a tool like Postman to test your connection. It lets you manually set proxy details and see if the issue persists. If it works there, the problem might be with your app’s configuration.

Also, try connecting to a different network (like mobile data) to see if it’s network-specific. Good luck!
Ugh, the "connection request failed 407" error is the worst. I fixed mine by resetting my proxy settings. If you’re on Windows, go to Settings > Network & Internet > Proxy and toggle off "Use a proxy server."

If that doesn’t work, try flushing your DNS. Open Command Prompt and type `ipconfig /flushdns`. It’s a long shot, but it’s helped me before.

Also, check if your firewall is blocking the connection. Sometimes it messes with proxy settings.
Thanks so much for all the suggestions, guys! I tried disabling the proxy in my network settings, and it worked! No more "connection request failed 407" error.

I’m still not sure why it was enabled in the first place, but I’ll keep an eye on it. If it happens again, I’ll definitely check out the tools you mentioned, like Fiddler and Postman.

Really appreciate the help—this was driving me crazy lol. Cheers!
Hey! The "connection request failed 407" error usually means the server needs proxy authentication. If you’re not using a proxy, your ISP might be.

Try this: Open your browser settings and look for "proxy." If it’s set to auto-detect, try disabling it. If that doesn’t work, you might need to manually configure it.

I’d also recommend checking out a site like whatismyipaddress.com to see if your IP is being routed through a proxy. If it is, contact your ISP and ask them to fix it.
Dude, I had the same "connection request failed 407" error last month. It’s 100% a proxy issue. If you’re on a corporate network, they probably require a proxy.

Try this: Open your app or browser settings and look for "proxy." If there’s a field for username/password, make sure it’s correct. If you’re not sure, ask your IT team.

If it’s a personal network, try disabling the proxy altogether. Sometimes ISPs force proxies, and it’s super annoying.
Hey! The "connection request failed 407" error is all about proxy authentication. If you’re using a proxy, make sure the credentials are correct.

If you’re not sure, try connecting without a proxy. On Windows, go to Settings > Network & Internet > Proxy and turn off "Use a proxy server."

Also, check if your app or browser has its own proxy settings. Sometimes they override system settings. If all else fails, try using a different network or contacting your ISP.
