Update it to report the _actual_ exception received. (If any.) At least then 
you will be sure.

So, no "ConnectionError" message?

Can you repost you code once it is modified to display the precise exception.

Note that one easy way to catch all but progressively handle specific 
exceptions looks like this:

  try:
     ... code ...
  except OSError as e:
    print OSError received, specifics are:", e
  except Exception as e:
    print "unhandled exception:", e
    break

and so on, inserting the exception types _above_ the final "except" as you add 
actions for them.
