If you are using proxychain for chaing proxy then need to get it http proxy for some reason(i.e set it on Telegram) you need to run some proxy server with this program. In this example I will use proxy.py. this is a http proxy server writed with pure python.
after config proxychains use following code.
pip install proxy.py
proxychains proxy
by defualt run http proxy on host 127.0.0.1
and port 8899
