Question: underwater photography

I have a newq 6020. I have taken a few regular photos that are great. Then I needed to charge the battery - yes a pain because charging is via the camera - anyhow we then went snorkeling here in Maui. Again a took 2 photos while the guys were getting ready and they looked good in the review screen. Then they tried to use the camera underwater and got a NO CONNECTION message. What Happened???? My friend made sure the camera case was locked before we entered the water, The battery also wanted to be recharged when we returned to the condo.
Does anyone have any suggestions? Thank you
