Why was dionysus mad at orpheus?

Dionysus was angry with Orpheus because, during his descent to the Underworld to retrieve his wife Eurydice, Orpheus failed to honor Dionysus and his rites. Instead of celebrating Dionysian festivities, Orpheus focused solely on his love for Eurydice, disregarding the god's influence and importance. In retaliation, Dionysus caused the Maenads, his female followers, to attack Orpheus, culminating in his tragic death. This punishment reflects Dionysus's demand for recognition and reverence in the face of human passion.
