java.lang.IllegalArgumentException: Host name may not be null

[WARN ] [org.openhab.binding.fritzboxtr064    ] - FrameworkEvent WARNING - org.openhab.binding.fritzboxtr064
org.osgi.framework.ServiceException: org.apache.felix.scr.impl.manager.SingleComponentManager.getService() returned a null service object

I wondered why he tells me, that the hostname is null - I specified the url.

Solution: Remove the (accidentally copied) point after IP address, then it works.
