Typo in error string
**Describe the bug**
Looking at this logged error string, there seems to be a space missing between "No route to hostrtsp://"

**To Reproduce**
setup a camera that can not be reached

**Expected behavior**
error string should be "No route to host rtsp://" with a space before the protocol
