SoapUI will ignore port information in URL

Hi all

if using this URL, the nextline (snap out of HTTP log) shows correctly the host including port:

URL:    https://10.0.20.48:49016/amopp/services/GWService

Wed Jan 10 16:04:46 CET 2018:DEBUG:>> "Host: 10.0.20.48:49016[\r][\n]"

In next example, the debug line shows up with missing port information in host; therefor getting a bad URL response

URL: https://post_test_amopp.giftcard.ch:49018/amopp/services/GWService

Wed Jan 10 15:53:14 CET 2018:DEBUG:>> "Host: post_test_amopp.giftcard.ch[\r][\n]"

Anyone a solution for that?

Many thanks
