TinyProxy doesn't work with a simple curl command

Hello,

First of all, thank you for your work : Deluge + Windscribe is working like a charm !

But I try to use TinyProxy and it doesn't work with a simple curl command. This command never ends :

curl -x http://localhost:8888 -L https://api.myip.com/

This is my config :

sudo docker run \
 -d \
 -v $PWD/config:/config \
 -v $PWD/rtorrent/download:/downloads \
 -e WEBPROXY_ENABLED=true \
 -e WEBPROXY_PORT=8888 \
 -e WINDSCRIBE_FIREWALL=off \
 -p 8112:8112 \
 -p 58846:58846 \
 -p 8888:8888 \
 --dns 8.8.8.8 \
 --cap-add=NET_ADMIN \
 --device /dev/net/tun:/dev/net/tun \
 --name deluge-windscribe \
 --restart=always \

Did I make a mistake ? Thank you for your help =)
