If your connection is lost after you bet, don't worry, your bet is still valid.

If this happens when you are playing in a slot game, go back and open the game again and it will continue from where you left off.

If this happens in a live casino game, your bet is also valid. The only difference is, you are not able to see what happens in the game round. If you win the bet, your winnings are added to your account immediately. If you want to see what happened in that game round, you can contact with Customer Service and ask for the screenshot.
