Volleyball skills have been off for months?
The timing is different for different areas of the net. Outside hitter to right side hitter etc. So now you have to relearn a new approach and timing as well as working with your setter. Perhaps have the setter set them a little bit higher for you so you can formulate a new approach. Then practice this until you are able to get used to the new approach. Also realize it takes time to get to know your new teammates, coach and their playing styles. Give yourself some time to get back in your groove. Otherwise go back to outside hitter?
