Looking at the bets, it seems that you used a 10.99× multiplier. x1.1 multiplier
0.00060390 × 10.99 = 0.006636861
Which is higher than your balance. So Primedice stopped the game.
Even if he used a x10.99 or any kinds of multiplier it should be betting without any errors maybe its on your connection sometimes i experience this kind of error in other dice sites when i leave the bot for hours trying to hit the jackpot.
Didn't you check what you quoted? It stopped because of insufficient balance. nothing related to internet connection or whatsoever
Maybe its just a visual bug on his browser side or primedice's side. The picture shows enough balance for the said bet though.
