Request 'ping' is not supported #638

One of our customers have ping disabled on their server. Whenever we pull or push big files we get the exception message below. So I am guessing it is because they disabled ping on their server. So my question is - is there a way I can disable the ping Request or other workaround? This issue does not happen if it is a small file and transmission completes quickly.
