Problem with api: transactions/address/

Hi all!

I have tried to get transactions for particular address.

The request 

`http://23.94.190.226:9081/transactions/address/kVVAu6F21Ax2Ugddms4p5uXz4kdZfAp8g`

returns:

`Ooops! The server was not able to produce a timely response to your request.
Please try again in a short while!`

Is it right that this method must return txs for any address ?
