Hi, I was running my python program to test the stability to get data through RTO(via internet).(it's not complete yet, still in development)
And on last Saturday, the Websocket just closed without any error.
So, my question is how do I write the program so that it re-connects after disconnection automatically?
And isn't run_forever() suppose to do that for me? Thank you.

You can check the market_price_rdpgw_service_discovery.py example on GitHub which demonstrates how to reconnect to the server.
def _on_close(self, ws, close_status_code, close_msg):
""" Called when websocket is closed """
self.web_socket_open = False
self.logged_in = False
print("WebSocket Closed for " + self.session_name)
if not self.disconnected:
print("Reconnect to the endpoint for " + self.session_name + " after 3 seconds... ")
time.sleep(3)
self.connect()

I assume that you are using the Python WebSocket Client library to establish a WebSocket connection to RTO.
You need to check if that Python WebSocket Client library can perform auto reconnection. Typically, I think that the Python WebSocket Client library may not support this. You need to check the document of that Python WebSocket Client library.
If the library doesn't suport reconnection, the application need to detect disconnections and has a logic to reconnect to RTO.
@Jirapongse I'm running the websocket in one thread while doing something in another thread.
Do I just start a new websocket thread in the on_close function so that when it's closed it will reconnect.
But it's just one time? If it closes the second time it won't be able to auto reconnect.
And correct me if I'm wrong but I'm pretty sure I can't start the same thread twice once it's terminated unless I re-start the program.
But the whole point of this is automation. If I have to re-start the program manually it's missing the point. Thank you.
After running the program for a few days, i got the following:
The following is my attempt to start a new thread in the on_close function:
But the "Connection is alive" stop after 20 seconds:
How should I go about reconnecting after disconnection automatically? Thank you.
