Getting Error 404 instead of json when trying to use daphne server and pagekite

Question

so I wrote a backend for my website with Python and FastAPI and now want to run it on my computer or phone. To run the python server I decided to use daphne, to make it reachable from a domain name, I've decided to use pagekite.

However, when I go to https://something.pagekite.me:8080/coordinates/?direction_x=1&direction_y=2&gas=2 (not the actual domain name), I get 404 Not found File or directory not found. Sorry! When I go to http://0.0.0.0:8000/coordinates/?direction_x=1&direction_y=2&gas=2 I get an actual json response I expect. Here are the commands I used to run main.py as the backend.

daphne -b 0.0.0.0 -p 8000 main:app

python3 pagekite.py --frontend=something.pagekite.me --service_on=http://0.0.0.0:8000

main.py:

from fastapi import FastAPI
from datetime import datetime
from pydantic import BaseModel
from fastapi.middleware.cors import CORSMiddleware

app = FastAPI()


origins = ["*"]

app.add_middleware(
    CORSMiddleware,
    allow_origins=origins,
    allow_credentials=True,
    allow_methods=["*"],
    allow_headers=["*"],
)

@app.get("/")
def root():
    return {"message": "Hello World"}

directionX = 0
directionY = 0
Gas = 0
@app.get("/coordinates/") #post is used to get data, but I can send it using get and query parameters response_model=Item)
def getcoordinates(direction_x,direction_y,gas): #http://127.0.0.1:8000/coordinates/?direction_x=0&direction_y=10&gas=50
    global directionX,directionY, Gas #changed async def to def 
    directionX = direction_x
    directionY = direction_y
    Gas = gas
    return {"data":(direction_x,direction_y,gas)}

Here is the whole pagekite log:

I use Linux Mint. Thanks for your help!

I see, but that is because of the automatic config of pagekite — Petr L., Aug 24 '21 at 20:29
If I change the port from 8080 to 8000 I get Temporarily Unavailable — Petr L., Aug 24 '21 at 20:30
If I understand the pagekite docs, you need `https://something.pagekite.me/...` without a port. It forwards port 80 or 443 to whatever local port you declared. — Tim Roberts, Aug 24 '21 at 21:07
@TimRoberts That produces the same result, Temporarily Unavailable when I go to it in Firefox — Petr L., Aug 24 '21 at 21:26
`-b 0.0.0.0` means "bind to all IPv4 addresses. You shouldn’t go to `0.0.0.0` in your browser or use it in the pagekite command. Use the actual IP instead, e.g. `127.0.0.1` or `192.168.100.3`. If you are running FastAPI in Docker, then you should include that info in your question. — Alasdair, Aug 25 '21 at 06:59
@Alasdair No, I don't use Docker. The 0.0.0.0 IP actually works but I will try your tip. — Petr L., Aug 25 '21 at 08:43
Cool, you mentioned Docker in one of your other questions, so I wanted to double check that you weren’t running FastAPI in Docker. — Alasdair, Aug 25 '21 at 09:41
@Alasdair 127.0.0.1 says unable to connect while 192.168.100.3 times out. — Petr L., Aug 25 '21 at 10:14
When I run hostname -I I get 10.0.0.19 172.20.240.0 172.17.0.1 2001:1ae9:1a:8500:7cb7:890:3ff1:f23e 2001:1ae9:1a:8500:439:17eb:ddf9:7cb5 — Petr L., Aug 25 '21 at 10:25
When I do daphne -b 172.20.240.0 -p 8000 main:app and visit that IP it works. When I do python3 pagekite.py --frontend=something.pagekite.me --service_on=http://172.20.240.0:8000 and visit the address in the browser, I get Directory listings disabled and index.html not found when I expected {"message":"Hello World"} — Petr L., Aug 25 '21 at 10:29
I haven't used page kite before so don't have any other suggestions. Hope you manage to get it working. — Alasdair, Aug 26 '21 at 10:24
@PetrL. try adding http in your command `python3 pagekite.py --frontend=something.pagekite.me --service_on=http://172.20.240.0:8000` — Chandan, Aug 27 '21 at 09:00
@Chandan That is the same adress. Will try, but if it is reachable from the browser, I don't know how adding http will help. — Petr L., Aug 27 '21 at 09:06
From your symptoms, it seems something related to a kite: A kite connects one or more services on your computer to a publicly visible DNS name or URL. — TASC Solutions, Aug 31 '21 at 23:46
@PetrL. have you tried this way `pagekite.py 8000 http:something.pagekite.me`. — Chandan, Sep 01 '21 at 02:20
@PetrL. [pagekite](https://pagekite.net/support/quickstart/) under `Kite management` section. — Chandan, Sep 01 '21 at 05:11
@Chandan Thanks it works! Write the answer so I can give the bounty to you. — Petr L., Sep 01 '21 at 11:19

When I do that in Termux, I get Error: Could not write to: /home/.pagekite.rc – Petr L. Sep 01 '21 at 20:20
@PetrL. the location should be inside user home folder where you have placed `pagekit.py`. – Chandan Sep 02 '21 at 04:44

you are using the wrong port for the link. instead of https://something.pagekite.me:8080/coordinates/?direction_x=1&direction_y=2&gas=2 try https://something.pagekite.me:8000/coordinates/?direction_x=1&direction_y=2&gas=2

If you read the comments, you would know that this is not the answer – Petr L. Sep 01 '21 at 11:16
oh sorry. i didn't think it would be in comments – Ayden Quinn Sep 01 '21 at 11:17
