I had the same problem, and the only solution for me (ubuntu 17.10, virtualbox 5.1.34 sandbox 2.5) were a new import in virtualbox.,
I had the same issue... i choose to import again the sandbox and worked.
With HDP_2.5_virtualbox I also facing the same issue. I tried to delete & to re-import but still does not work.
I have tried both the setting, but nothing works for me. Please let me know if any solution comes out. firstname.lastname@example.org
