My vanda orchid flowered 3 times without problem, then for the last 2 times, the flower dried before opening and I have not moved the plant. It is attached to a palm tree. What do you suggest?

The flower issue is likely environmental issue. To hot, lack of humidity or even to wet of conditions may certainly be the problem.
Inspect the plant and roots to rule out disease. You can treat any issues if found, with Neem Oil.
This works and both an insecticide and fungicide.
