"Ugh, 'your server did not send a forwarding request to proxy' error – anyone else hit this?"

So my setup was working fine, then BAM – this error pops up outta nowhere.

From what I can tell, it’s usually a misconfig between the server and proxy (duh). Maybe headers aren’t passing right or the proxy’s expecting something the server ain’t sending.

Tried checking the proxy logs? Sometimes the answer’s just sitting there, laughing at you.

Also, double-check your proxy_pass settings in Nginx/Apache. If it’s ignoring the X-Forwarded-For header or similar, that’s probs the culprit.

Any quick fixes? Restarting the proxy/service *might* help (lol, classic), but if not, you’re in for some config tweaking.

Anyone got a magic bullet for this? Share your wisdom pls!
Oh man, I feel your pain. Had the same 'your server did not send a forwarding request to proxy' error last week. Turns out my proxy_pass directive in Nginx was missing the trailing slash.

Fixed it by adding `/` at the end of the proxy_pass URL. Worth a shot if you're using Nginx. Also, check out the Nginx docs on proxy settings—super helpful.
Classic proxy woes, huh? The 'your server did not send a forwarding request to proxy' error usually means the server and proxy aren’t playing nice.

Try adding these headers to your proxy config:
`proxy_set_header Host $host;`
`proxy_set_header X-Real-IP $remote_addr;`

If that doesn’t work, maybe your proxy’s caching old configs. Clear the cache and restart.
Ugh, this error is the worst. Had it happen when my backend server was overloaded and stopped responding to the proxy.

Quick fix? Increase timeout settings in your proxy config. Also, tools like `curl -v` or Postman can help debug what’s actually being sent between server and proxy.
Yep, ran into this too. The 'your server did not send a forwarding request to proxy' error often pops up when the proxy expects HTTPS but the server’s sending HTTP (or vice versa).

Double-check your scheme (http:// vs https://) in the proxy_pass directive. Also, tools like mitmproxy can help sniff the traffic and see where it’s breaking.
OP here. Wow, thanks for all the suggestions! Tried the trailing slash in proxy_pass and adding the X-Forwarded-Host header, but no luck yet.

Gonna dig into the proxy logs next—anyone know the best way to filter for this specific error? Also, is there a way to force the server to log the exact request it’s receiving? Appreciate the help!
This error drove me nuts until I realized my server was blocking the proxy’s IP.

Check your server’s firewall/security groups to make sure the proxy IP isn’t blacklisted. Also, `tcpdump` is a lifesaver for seeing if the request even reaches the server.
Had this exact issue yesterday! The 'your server did not send a forwarding request to proxy' error was because my server was redirecting without preserving the original Host header.

Fixed it by adding `proxy_set_header X-Forwarded-Host $host;` to my Nginx config. Maybe give that a try?
Sounds like a header mismatch. The proxy’s waiting for something the server ain’t sending.

Try enabling debug logs on both the server and proxy. Also, check out the Proxy Protocol—it’s a game-changer for these kinds of issues.
Been there! The 'your server did not send a forwarding request to proxy' error can happen if your server’s SSL cert is expired or misconfigured.

Run `openssl s_client -connect yourserver:443` to check the cert chain. If it’s busted, the proxy might just give up.
