Transfer again after the first transfer is finished

An invalid request was sent. This problem can occur when two Trivial Transport Protocol (TTP) operations are performed simultaneously. TTP is used when an application does not support the transfer of data using POST methods and must instead carry the data within the URL in the form of query string variables. Try again after the first transfer is finished.
