    Give it enough memory. Jan 20, 2021 at 16:41
  • Yes i will take another droplet with 1gb 1cpu . I am not sure which is better choose to move it ue4 server or mongo on new clear server. If i move mongo than i need to allow remote connection which is bad idea . I am already feel brutal force in that case. Jan 20, 2021 at 16:48
