Hi Brian,
thank you very much for your response!
I just wanted to clarify, if it's better to "regex" the port to the end of
the address, or if it is equally fine to just add the port in the
target.yml to each target? (That's what im currently doing) Is it just best
practice with the regex expression or is there actually a technical reason
behind that?
Kind regards
Kolja
