Px proxy "Connection Refused" (Windows 10 with WSL1)

[moyscode]

I run a Px instance on my Windows 10 with the following content in my px.ini file

[proxy]
server = company-proxy-sl.company.com:8080
listen = 
port = 3128
gateway = 0
hostonly = 1
allow = 
noproxy = 127.0.0.*,10.*.*.*,192.168.*.*,localhost*
useragent = 
pac = 
username = 
auth = 

[settings]
workers = 3
threads = 8
idle = 30
socktimeout = 20.0
proxyreload = 60
foreground = 0
log = 1

Px is working fine. Now I try to connect to the server has from within WSL (Ubuntu 16.04).
Within WSL, I have ~/.bashrc file with the content as below
export http_proxy="http://localhost:3128" export HTTP_PROXY="http://localhost:3128" export https_proxy="http://localhost:3128" export HTTPS_PROXY="http://localhost:3128" export no_proxy="localhost,127.0.0.1,::1,localhost*" export NO_PROXY="localhost,127.0.0.1,::1,localhost*"

All my proxy env vars (http_proxy, https_proxy, HTTP_PROXY, HTTPS_PROXY) are set to http://localhost:3128.

However, when I run curl www.google.com on WSL, I get the error curl: (7) Failed to connect to localhost port 3128: Connection refused

My colleagues have the same configuration & everything works for them!

Does Px show any connection from curl in the debug output? Is it Px that is refusing the connection or does it not even get the request?

I've not used WSL but wondering if there's any firewall involvement between the Windows and Linux sides.

—hostonly already overrides listen so you might want to disable that. Also, on the command line, you just set —listen=127.0.5.1.

[moyscode]

Oh. OK. I made the change. But in debug mode. I get Client not allowed: 127.0.0.1 (Pic below) after I start Px in debug mode

[genotrance]

So are you in host only mode or did you set listen?

[genotrance]

Also, did the request come from windows or WSL?

[moyscode]

I am in hostonly mode. I did not make any requests at all. From either Windows or WSL. Those Client not allowed: 127.0.0.1 very generating by themselves.

Well something is trying to access Px - its likely coming cause you have set http_proxy in your bashrc and something is picking it up.

I'll suggest removing the http_proxy entry and testing with curl --proxy localhost:3128 www.google.com for now from both Windows and WSL and see whether Px gets the requests first. Try this with --hostonly.

Next, disable host only and see if the Px default works (listening to localhost only). Next, you can try adding a specific --listen, then followed by an explicit --allow list as well. Basically, build your own host only mode. There might be a bug somewhere.
