Welcome to the Ranch!

I'm not sure that the error lies in your code, but is instead a network issue. Can you telnet to the port, or connect otherwise?


By the way, I've added code tags this time. Can you please add them yourself next time? It makes your code more readable.

I still suggest having a closer look at the infrastructure. If the problem is intermittent, it also means that sometimes it works, which is an indication the problem lies outside of your code.

That (usually) indicates the other side has closed the connection. That's hardly ever your fault.
 
Don't get me started about those stupid light bulbs.
