Python Twisted Client Connection Lost

I have this twisted client, which connects with a twisted server having an index. I ran this client from command-line. It worked fine. Now I modified it to run in loop (see main())

Solution 1:

You don't quite understand how the Twisted reactor works.

reactor.run() is starting up the reactor's event-loop --- it's a blocking call that loops "forever".

See http://twistedmatrix.com/documents/10.2.0/core/howto/reactor-basics.html for various reactor-related topics.
