Also got this error last night, I used chrome browser on Desktop, bet amount 10 satoshi both with eth. when you read post above, you will see same problem with phone, look like your server problem.
Below post by OP is the reason for the problem you got:
The reason you cannot place bets with ETH, is beacuse the bankroll is too low. 
Similar post was made earlier when OP answered my question about ETH bankroll which is only 0.00000001ETH
If the problem occurs when you bet with btc then it is a different problem that needs to be fixed.
But if the problem occurs with ETH bet only then it is simply because the site has no ETH bankroll to pay ETH bets.
Why would they put ETH on the options if they dont have sufficient fund into their hot wallet? Its just nonsense if they wont replenish the balance because we know that there are people who do make use of ETH
into their bets and if they dont consider on putting ETH then why put it on the first place? unless if they would do it later on.
Bankroll is needed and its no brainer that a site should have because how you would pay out users or winners if you dont have money to pay on?
but they had mentioned that they are still on Beta phase then it might be the possible reason.
Where they have mentioned that the site is in beta phase ?
If the site is in beta phase they should have mentioned this on the site but i don't see any such information on https://robodice.io/.
