Solved: the 5'th server I tried (HTTP) worked just fine!
well, First I used the Cygwin installer to install (using admin rights) installed for (all users)
then it said installation complete;
I tryeed to run cygwin.bat (with/without) admin rights;
I got this
---------------------------
bash.exe - Unable To Locate Component
---------------------------
This application has failed to start because cygreadline6.dll was not found. Re-installing the application may fix this problem.
---------------------------
maybe I have to update the PATH or something
