You can increase timeout for request (if you use DirectEvent then use Timeout property) but i am strongly recommend to redesign your server side handler for that ajax request
I am having this issue too - it works fine locally, but gets a "communication failure" error on the server. I have a timeout of 600000 on my DirectEvent, but it still fails after 30 seconds or so, so that is not the issue.
