If you have a large number of ships in the fleet, they can block the way for your troop transport to make it to the planet; in or out of formation. The situation is worse if they are not in formation or you have a very "tight" formation with no room for the TT to get through. If your Troop Transport can't get next to the planet, no troops can land. For large fleets I recommend staying in formation, and pick a "loose" formation that can allow the TT through from behind since the TT initially runs away and usually has to get through your fleet to make it to the planet.
