I have recently signed up for a free account and I am a beginner. This is what my code is trying to do - just posting a hello message via slack webclient
client = slack.WebClient(token=slack_token, proxy="http://proxy.server:3128")
client.chat_postMessage(channel="random",text = "Hello from Python Anywhere")
however when I try to run it throws error pasted below
aiohttp.client_exceptions.ClientHttpProxyError: 403, message='Forbidden', url=URL('http://proxy.server:3128')
I looked in different topics for help, everywhere it suggested about whitelisting issues but i believe api.slack.com is already whitelisted. Please help.
