Hi, I am sorry. I am a newbie Is it possible that we can check if the server still alive or crashed or network interface down from the server code side?

Thanks

call check_connection which will throw an exception on connection lost.

while True:
     await asyncio.sleep(1)
     await client.check_connection()  # Throws a exception if connection is lost

Hi, Is there an attribute of server status or internal the server status that we can check the server status is running or failed

No this currently not possible.

what do you mean with running? tcp socket? processing ua requests?

this is not so easy to do opc ua has a layered architecture...
