Error deploying from ethereum studio to ropsten

Question

I tried to deploy a contract to ROPSTEN from Ethereum Studio using "send contract to the Net" with the following parameter:

JSON RPC URL: https://ropsten-lb.ether.camp

It is actually an small oraclize tutorial contract (Contract DieselPrice).

My deploying address (0x101a23558277e7b8c6b9642b3a0650d03fd2bdb5) has 3 ethers on ropsten.

I get the following error: "getaddrinfo ENOTFOUND ropsten-lb.ether.camp ropsten-lb.ether.camp:443"

Has anyone experienced such error?

Could not get gas price from https://ropsten-lb.ether.camp: getaddrinfo ENOTFOUND ropsten-lb.ether.camp ropsten-lb.ether.camp:443
