SignalR client.start() function blocked after keepalive timeout error

[supremeremixx]

Hello!
I'm trying to run endless loop with SignalRClient.

import time
import logging
from fastf1.livetiming.client import SignalRClient

log = logging.getLogger()
log.setLevel(logging.DEBUG)

def signalr():
  client = SignalRClient(filename="output.txt", timeout=1800, debug=True)
  client.start()

while True:
  signalr()
  time.sleep(60)

After random amount of time (3, 5 , 11 hours...) I get keepalive timeout error. In logs I see that TCP connection is closed, but function client.start() still blocked, it never ends. Loop is never finished and that's why program not creating a new client instance after error.

I've tried running it with and without timeout (in SignalRClient), but the function remains locked.
Is it possible to somehow terminate it after receiving an error?

Hi, I'm really not sure what causes this and how to fix it at this stage. I've never seen this error myself, and it's the first time it has been reported.
I agree that .start() should not remain blocking but instead return. But I am not sure how soon I'll realistically get around to fixing this.

I've opened #628 to track this as an issue.
