Bug: Logs flooded with "Proxy-Authorization header not found" after setting HTTP User, Password #1398

Open Stylback opened 1 year ago

Stylback commented 1 year ago

Is this urgent?

No

Host OS

Ubuntu Server 22.04 LTS

CPU arch

x86_64

VPN service provider

Mullvad

What are you using to run the container

docker-compose

What is the version of Gluetun

Running version latest built on 2022-12-31T17:50:58.654Z (commit ea40b84)

What's the problem 🤔

Tl;DR: Other containers trying to use the Gluetun-container's HTTP proxy will produce a log entry for every request with INFO [http proxy] Proxy-Authorization header not found from [docker-ip]:[port].

Hi! I've been spending the last few evenings testing out Gluetun. I have a media stack (qbittorrent, *arr, jellyfin) where each service have their own docker container. My goal have been to have a Gluetun container with Mullvad which I then could use as a proxy for other containers.

I noticed that if I have the HTTPPROXY_USER and HTTPPROXY_PASSWORD environment variables enabled, each service that connect to Gluetun's HTTP proxy with the given credentials will produce a log entry claiming the incoming request lacks a Proxy-Authorization header. The service will however still be able to complete its requests without issue.

This behaviour seems contradictory. I don't know if this is an inteded behaviour (did not see another issue on this) or if there is a missconfiguration on my end. Either way it is currently flooding my logs and I hope there is a way to resolve this without disabling proxy authentication.

I am seeing the same thing on my end. Services can connect to the proxy just fine but my logs are littered with these messages. Is this a configuration error on my part?
