Workflow serve reports empty IP address

When serve workflow is started and arbitrary file is requested, dd2go reports '[' instead of IP address.

This behavior was so far observed:

• on Windows
• when accessing file from localhost (remote connections were handled correctly)

PS C:\Users\user\tmp> .\dd2go-windows-amd64.exe serve
