A number of things can actually causes this. The most common is over-shearing, which leads to thick outer growth and blocks sunlight from inner branches of the shrub. Root or crown rot is another possibility, as are other diseases and pests. These articles will help with rot issues: https://www.gardeningknowhow.com/plant-problems/disease/crown-rot-disease.htm

Generally, it helps to prune out the interior, opening it up to air and light, or even some rejuvenation pruning, though this drastic measure may limit blooming next season.
