"Max retries exceeded with url"-error when using handle_available()

[vincentscode]

The API crashes about every 5 minutes when using the code below.

def turn(board, symbol):
    # some code
    return x, y
api = BOAIapi(turn, verbose=1)
while True:
    api.handle_available()
    time.sleep(5)

The stacktrace:

Fri 13:18:02 [BOAIapi] handle_available: Handled 170 (Not your turn)
Fri 13:18:02 [BOAIapi] handle_available: Handled 171 (Not your turn)

My Solution

Since I did not find any piece of code in the backend that would trigger such behavior, I assume that the problem is on the client side (caused eg by short disconnects at an unfavorable time) or directly on the server. On the client side, I couldn't find anything better than a try / except for this problem, which I have implemented for me and it works great so far. On the server side, I have absolutely no plan and can't do anything anyway.

If no one else encounters this problem i assume that it was a local problem and can be resolved by the steps described above.
