While True stops working after a while?

Question

Python

I have a piece of code that constantly checks if it's time to do something (these actions should be repeated every 15 minutes and every 8 hours)
I use the while True construct and in it I have:

while True:
        if profit_time <= datetime.datetime.now():
        collect_profit()
        profit_time = profit_time + datetime.timedelta(hours=8)
        info_log(f'| Деньги будут собраны в {profit_time}')
    elif underwork_time <= datetime.datetime.now():
        underwork()
        pets_battle()
        underwork_time = datetime.datetime.now() + datetime.timedelta(minutes=15)
        info_log(f'| Следующие действия будут выполнены {underwork_time}')
    else:
        time.sleep(2)

Also, at the beginning of the program I have variables:

underwork_time = datetime.datetime.strptime(start_date, "%Y-%m-%d %H:%M:%S") + datetime.timedelta(minutes=15)
profit_time = str(datetime.datetime.now().strftime('%Y-%m-%d')) + str(datetime.datetime.now().strftime(' %H:%M:59'))
profit_time = datetime.datetime.strptime(profit_time, "%Y-%m-%d %H:%M:%S")

On pythonanywhere, after 3-5 iterations, the program just stops. What to do?

Answer 1

Press CTRL+C and see the traceback. See what exactly was running at that moment.
And do you have HTTP requests to external servers there, for example, through requests? So when no timeouts are specified, these calls can hang during the connection setup phase without causing an error.
