error 400 for just a delivery service

[amirhossein ramezan <am...@yahoo.com.INVALID>]

Unfortunately, I encountered a strange problem. Please guide me if anyone can help. I made a new DS, but I can't get any of the origin content with the cdn link. and edge and mid show error 400. If the content can be received with wget on both mid and edge servers. Could it be for http headers? I will also send the headers below. The log displayed in mid for not receiving content is ERROR_TCP_MISS 502

What could be the reason and what should I check?

Hi-
  ERROR_TCP_MISS_502 (Bad Gateway) typically means ATS cannot connect to
the origin server. Since you can retrieve content with wget on the mids,
this could be a mismatch in configuration somewhere. Double check
parent.config and remap.config.

If still not working, you could try running a tcpdump on one of the caches
to see where trafficserver is attempting to send the traffic to.
