Data restore from old system

Hello All,

we have a legacy HP server in which DP 9.0 is installed and backup was configured directly on HP tapes. we had shutdown the server as we moved to another brand Dell servers as well as new version of DP 10.40.

HP serer was shutdown since June 2018. unfortunately I want to recover some data before June 2018. when i try to open DP in HP server  it's give the error "couldn't connect to host"

Error Screenshot attached.
