then it is no wonder you are unable to receive a signal, the signal path to the LNB is not coming from the Clarke curve. Firstly you need to determine the offset angle of the dish. If that is your dish in your profile then as Puerto Rico is at latitude 18.2 deg North (not dissimilar to the UK), and your dish is a standard 22deg offset then the dish face should be almost vertical. Viewed from where you are in Puerto Rico the top dead centre i.e. the top of the arc for your longitude are 65 deg West or 67 deg West because your latitude and longitude are 18.24914° N, -66.62804° E (66.62804W)
So first find one of those as a starting point
Your dish should look something like this
