Fixes

• Fixes the login window display during the Trial or to register a Full License
• Fixes connection problems when a service is only accessible through IPv6 while DNS returns also an IPv4 address (e.g. the local PHP test server only accept IPv6 by default, while often "localhost" is configured for both IPv4 127.0.0.1 and IPv6 ::1). If you were experiencing issues to connect to a local server, this should fix the issue.
• Fixes IPv6 addresses parsing (e.g. http://[::1]:8000)
