I’m stuck on Stage #AP6

Not going to lie, I changed my port before to 1142 because I was testing out what would happen if I changed my port and now that I changed it back to 4221, it won’t work anymore. Note that 4221 is the port I’m supposed to be connected to

Here are my logs:

```auto
remote: Running tests on your code. Logs should appear shortly...
remote: 
remote: [tester::#AP6] Running tests for Stage #AP6 (Return a file)
remote: [tester::#AP6] $ ./your_server.sh --directory /tmp/data/codecrafters.io/http-server-tester/
remote: [tester::#AP6] Testing existing file

remote: [your_program] Waiting for a connection...

remote: [tester::#AP6] Test failed (try setting 'debug: true' in your codecrafters.yml to see more details) 

```

And here’s a snippet of my code:

```python
import socket
import threading
import os

def read_files(data, connection, address):
    method = data.split(' ')[0]

    if method == 'GET':
        directory_files = os.listdir('tmp')
        requested_file = data.split(' ')[1][5::]

        if requested_file in directory_files:
            file_path = os.path.join('tmp', requested_file)

            with open(file_path, 'rb') as file:
                content = file.read()
                file_size = len(content)

            header = f"HTTP/1.1 200 OK \r\nContent-Type: application/octet-stream\r\nContent-Length: {file_size}\r\n\r\n".encode()

            connection.sendall(header)
            connection.sendall(content)

        else:
            connection.sendall(b"HTTP/1.1 400 Not Found\r\n\r\n")

def handle_connection(connection, address):
    try:
        data = connection.recv(1024).decode("utf-8")
        path = data.split('\r\n')

        read_files(data, connection, address)

    finally:
        connection.close()

def main():
    server_socket = socket.create_server(('localhost', 4221))
    server_socket.listen()

    print('\nThe server is starting..')
    print('Waiting for a connection..\n')

    count = 0
    while count < 1:
        connection, address = server_socket.accept()
        
        client_handler = threading.Thread(target=handle_connection, args=(connection, address))
        client_handler.start()

        count += 1

if __name__ == " __main__":
    main()

```

Try setting _reuse\_port_ to True in _create\_server_

You shouldn’t need `reuse_port`, should work without it.

@iExcilsior Just changing the port and back should’ve worked as long as other code didn’t change. Can you try comparing to a previous commit that passed and seeing what changed from there?

hey man, thanks for responding! I did check my previous commit, nothing really changed much except when I changed my port (which is now redundant)

The last successful commit I see is `8490399afe079bcd51da2b31c6e7c83261c0671b`. Could you try resetting to this and running tests?

```auto
git reset --soft 8490399afe079bcd51da2b31c6e7c83261c0671b
codecrafters test

```

The `--soft` flag ensures that no changes are committed.

If that code works, then you should be able to work your back and figure out what change caused this recent issue.

</div>

oh hey! am I also supposed to run codecrafters test? I’m running it on git bash but it says codecrafters: command not found. Sorry, I’m not knowledgeable around these.

But I did execute the commands and ran these:

```auto
git add .
git commit --allow-empty -m "pass stage"
git push origin master

```

To test out my code but it showed this

```auto
To https://git.codecrafters.io/735c9452fbfe568d
 ! [rejected] master -> master (non-fast-forward)
error: failed to push some refs to 'https://git.codecrafters.io/735c9452fbfe568d'

hint: its remote counterpart. Integrate the remote changes (e.g.
hint: 'git pull ...') before pushing again.
hint: See the 'Note about fast-forwards' in 'git push --help' for details.

```

What do I do next?

</div>

Try the same with `git push -f origin master` (when you do “git reset”, your git history changes, and you need to use `-f` which stands for `--force`)

Ahh, makes sense. I did do as you instructed. I did reset it, did the commands that include ‘-f’ and all but it still failed to make a connection. What else can I try?

Are you sure you followed the commands exactly? I’m looking at logs and I see that different code was pushed.

To clarify, here’s what you need to run:

```auto
git reset --soft 8490399afe079bcd51da2b31c6e7c83261c0671b
git add . 
git commit -m "something"
git push -f origin master

Oh I see, that’s my fault. I just finished following the commands. It still failed to connect

Still doesn’t look like the correct commands were executed.

```auto
git reset --soft 8490399afe079bcd51da2b31c6e7c83261c0671b
git status
git add . 
git commit -m "something"
git push -f origin master

```

Can you run each of these and share the exact output you see? (Terminal screenshot will do)

I’m particularly interested in the output of `git status`. That should show multiple files changed. Here’s what I see locally:

Hello, I did as you instructed. Here are the screenshots of my terminal

since I have an extra file (test.py) I’ll try to migrate the code inside that to my main.py. I’ll see if that works
