@HexMAge

aaaaaaaaaaaaaaaaaaaajjj... ale ze mnie pała..
masz rację, nie zauważyłem tego zerowania, został jakiś śmieć,
działa bardzo dobrze teraz jak należy, jak niema kabla to czeka np. 1 sekunde i koniec.

wielkie dzięki

jeszcze spróbuje zrobić sposobem @docenta, to chyba by był bardziej uniwersalny bo nie trzeba by
wybierać sobie serwera.. ale póki co jest git.. taki sposób też wystarczy.
