The messages suggest there is something wrong with the proxy in 
question, most likely it fails to handle chunked encoding 
properly.  You may try to disable use of chunked transfer encoding 
with

    chunked_transfer_encoding off;

to see if it helps.  Note though that it will also make keepalive 
connections impossible if Content-Length isn't known.  You may 
also try to disabling keepalive connections completely with

    keepalive_timeout 0;

See here for details:
