Minimum air leaking, more of a water leaking

Hi, I just fixed air leaking and now it leaks water..I changed the nuts on the hose and the air is leaking minimally now..I dont know if I can tighten it more because I tried with the broken nut which I glued together and it separated again while tightening

I have some older version of Sodastream than that
