Error while trying to sync testnet

i keep getting a “java.util.NoSuchElementException: next on empty iterator” trying to sync the testnet ether locally on on a VPS with digital ocean, any idea ?

The sync of the test net is creating a problem and the localizing on a VPS with the digital ocean is not getting accessed and the java code is not getting executed. To know more Apple iPad support

Thank you, actually the problem was fixed by disabling the matcher in conf file.
