Proxied DNS blocks server connections.

I am back. I have created an HTTP website on port 80, but I am still getting the connection blocked by CloudFlare. Maybe I don't know how to configure my CloudFlare settings correctly. I tried an alternative service and successfully created a reverse proxy for my server. I will continue using CloudFlare for the website and configure the server backend using the alternative service. @HardlyWorkin' Thank you for your time and effort in trying to help me. 🙏🙏🙏

With tunnel. direct IPv4 works fine but switching to the tunnel URL gets blocked by CloudFlare

Oh it's not even reaching the server, I get no prints from the server at all so CloudFlare is blocking the access.

That is what the client is receiving from the server, the server doesn't print anything. Here are the scripts for context: server.py

import socket
import ssl
import os

HOST, PORT = '0.0.0.0', 2053

certfile_path = os.path.expanduser('~/Projects/Test-cf/cert/origin_cert.pem')
keyfile_path = os.path.expanduser('~/Projects/Test-cf/cert/private_key.key')

sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.bind((HOST, PORT))
sock.listen(1)

context = ssl.create_default_context(ssl.Purpose.CLIENT_AUTH)
context.load_cert_chain(certfile=certfile_path, keyfile=keyfile_path)

wrappedSocket = context.wrap_socket(sock, server_side=True)

print(f'Server is running on {HOST}:{PORT}...')

while True:
    try:
        client_socket, address = wrappedSocket.accept()
        print(f'Connection from {address}')
        
        try:
            data = client_socket.recv(1024)
            print(f'Received: {data.decode("utf-8")}')
            if data:
                response = 'Hello World'
                client_socket.sendall(response.encode('utf-8'))
        finally:
            client_socket.close()
    except Exception as e:
        print(f'An error occurred: {e}')

wrappedSocket.close()

import socket
import ssl
import os

HOST, PORT = '0.0.0.0', 2053

certfile_path = os.path.expanduser('~/Projects/Test-cf/cert/origin_cert.pem')

sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

sock.listen(1)

context = ssl.create_default_context(ssl.Purpose.CLIENT_AUTH)

            if data:
                response = 'Hello World'
                client_socket.sendall(response.encode('utf-8'))
        finally:
            client_socket.close()
    except Exception as e:
        print(f'An error occurred: {e}')

wrappedSocket.close()

client.py

import socket
import ssl

HOST, PORT = 'tunnel.domain.com', 2053 #'tunnel.domain.com' is a placeholder for my domain

ca_cert_path = 'cert/origin_cert.pem'

context = ssl.create_default_context(ssl.Purpose.SERVER_AUTH)

context.load_verify_locations(ca_cert_path)

context.check_hostname = True

with socket.create_connection((HOST, PORT)) as sock:
    with context.wrap_socket(sock, server_hostname=HOST) as ssock:
        # Send data
        ssock.sendall(b"ping")
        
        response = ssock.recv(1024)
        print(f"Received: {response.decode('utf-8')}")

import socket
import ssl

HOST, PORT = 'tunnel.domain.com', 2053 #'tunnel.domain.com' is a placeholder for my domain

ca_cert_path = 'cert/origin_cert.pem'

context = ssl.create_default_context(ssl.Purpose.SERVER_AUTH)

context.load_verify_locations(ca_cert_path)

context.check_hostname = True

with socket.create_connection((HOST, PORT)) as sock:
    with context.wrap_socket(sock, server_hostname=HOST) as ssock:
        # Send data
        ssock.sendall(b"ping")
        
        response = ssock.recv(1024)
        print(f"Received: {response.decode('utf-8')}")

I am unsure if my method of including the certification is correct, I had copied 'Origin Certificate' and the 'Private Key' into a text file and changed the file into .pem and .key

It's a very short python script I am testing this on, I can post it incase there is a method to include the certificate that I am not aware of.

By server log you mean the full '400 request error' or something specific within CloudFlare?

I created and tried to use 'Origin Certificate' on my hostname and server but it didn't help, Would it be beneficial If I shared the python server and client code I am using to diagnose if It's a code related issue?
