Why Twitter is not making a get request to my server while registering webhook using endpoint? - twitter

Question

I'm using twitter account activity api for registering a webhook using autohook wrapper library.
As per the docs the post requests to endpoint (https://api.twitter.com/1.1/account_activity/all/:env_name/webhooks.json) should trigger a get request from my server. that will return a crc based on a crc token and my consumer key.
While im getting code 215 and unable to connect during crc request error message again and again.
Im not sure why get request is not exceuting. here is my server and client code.
server.py
#app.route("/webhook/twitter", methods=["GET", "POST"])
def callback() -> json:
if flask.request.method == "GET" or flask.request.method == "PUT":
print(flask.request.args.get("crc_token"))
hash_digest = hmac.digest(
key=os.environ["consumer_secret"].encode("utf-8"),
msg=flask.request.args.get("crc_token").encode("utf-8"),
digest=hashlib.sha256,
)
return {
"response_token": "sha256="
+ base64.b64encode(hash_digest).decode("ascii")
}
elif flask.request.method == "POST":
data = flask.request.get_json()
logging.info(data)
return {"code": 200}
# Once the code running on the server.
# You can register and subscribe to events from your local machine.
#app.route("/",methods=["GET"])
def callbackget():
return "in GEt"
if __name__ == "__main__":
app.run(debug=True, port=443,ssl_context=context)
client side autohook wrapper:
const { Autohook } = require('twitter-autohook');
(async ƛ => {
const webhook = new Autohook(
{
token:"1218220064610099203-8CnN6G3edmIRGdDpLcR7Bao88mMCUg",
token_secret:"JEavuf3PZmSsXWhmSdtNarFPNBp6BsZzMrLpkEMASkJX5",
consumer_key:"6n7U6KDXxouXDcsLMxdiSKwZ9",
consumer_secret:"o2aKE9TivbTwchJXXZ4XaTyAwtCgtoRO35a9PgdaqMLUBRfv49",
env:"enc"
}
);
// Removes existing webhooks
await webhook.removeWebhooks();
// Listens to incoming activity
webhook.on('event', event => console.log('Something happened:', event));
// Starts a server and adds a new webhook
await webhook.start("https://127.0.0.1:443/webhook/twitter");
// Subscribes to a user's activity
await webhook.subscribe({oauth_token, oauth_token_secret});
})();
