Issues with KNX Gateway Automatic Discovery since #129 was introduced #208

With v2.3.0 the KNX Gateway Automatic Discovery works as expected.

However, starting with version 2.3.1-b2 (which coincides with the introduction of #129) auto discovery no longer works for me.

However, if I manually set the IP and protocol (UDP), then the latest bits work.

You are right, version 2.4.0 uses TCP by default for new tunnel connections. I've changed that in 2.4.1-b3 where UDP is used by default.

Only downside is that existing users have to choose UDP in Settings because TCP is already selected for them.
