This is an issue with using an IPv6 loopback address. Just use localhost or 127.0.0.1 instead of ::1.

The exact error you are seeing is coming from requests I think? But just use an ipv4 address.

Additional, why are you running run_server in a thread? The whole point of this package is so that you can use ServerThread without doing that.

Here's my version of your example:

import requests
from fastapi import FastAPI
from server_thread import ServerThread

SERVER_HOST = "127.0.0.1"
SERVER_PORT = 24643
app = FastAPI()


@app.get("/")
def howdy():
    return {"Howdy": "World"}


# app.mount("/static", StaticFiles(directory=os.path.join(parent_dir,"static")), name="static")

server = ServerThread(app, host=SERVER_HOST, port=SERVER_PORT)

print(f"http://{server.host}:{server.port}")
response = requests.get(f"http://{server.host}:{server.port}/")
response.raise_for_status()

I am stealing idea from some repo for build a small gui. use run_server because there is a later monitor server function

    monitor_thread = Thread(
        name="Thread monitor",
        target=monitor_threads,
        args=(server_thread,),
    )
    monitor_thread.daemon = True
    monitor_thread.start()
    


def monitor_threads(*threads):
    while True:
        for thread in threads:
            if not thread.is_alive():
                logger.critical(f"Thread: {thread} died, exiting!")
                quit_window(icon=None)
                server.stop()
                sys.exit(2)
        else:
            sleep(0.5)

Okay

I'm going to consider this resolved as this should all work fine if using an IPv4 address

[wanghaisheng]

how to check server is alive?@banesullivan
can we just get the thread you start

the same code will give me diff out

[banesullivan]

Please see my comment about not using ::1 as your SERVER_HOST: #4 (comment)

[wanghaisheng]

no as you can see I print my host and port input first,both case input is the same

try to start server 127.0.0.1:0

[banesullivan]

Apologies, I missed that in all the logs. I wonder if this is a compatibility issue with uvicorn or werkzeug on Windows.

What if you use "localhost" instead of 127.0.0.1?

[wanghaisheng]

I can test this hypothis from my windows and mac tomorrw
