It seems that, at least in older versions, "Miranda" does not support
the "chunked" encoding which is mandatory for the HTTP/1.1 clients.
Here is a workaround by DeleGate to cope with such case:

  HTTPCONF=bugs:no-chunked  ## suppress chunked encoding toward clients

Or more safely suppress HTTP/1.1 features completely:

  HTTPCONF=clver:1.0        ## suppress HTTP/1.1 features with clients

And your log shows many other implications of problematic situation of
your environment which might be mitigated with following parameters.

  REMITTABLE=+,ssltunnel    ## allow non-HTTPS/SSL communication over SSLtunnel
  MAXIMA=contry:1           ## suppress the retrial of TCP connection
  TIMEOUT=con:5             ## shorten the timeout of a TCP connection trial
  TIMEOUT=dnsinv:1          ## shorten the timeout of an inverse DNS lookup
