ORDER OF AFFIRMANCE
Appellant Corey B. Johnson challenges the district courts August 31, 2021, order denying several pleadings treated collectively as a habeas petition challenging the revocation of Johnsons parole and the computation of his credits. Johnson previously filed a postconviction habeas petition challenging the parole revocation, which the district court denied in a November 25, 2020, order. As that decision was on the merits and Johnson has not alleged new or different grounds in the instant matter, the petition was successive. NRS 34.810(2). The petition was thus procedurally barred absent a showing of good cause and actual prejudice, which Johnson did not plead. See NRS 34.810(3). The district court therefore correctly applied the mandatory procedural bar. See State v. Eighth Judicial Dist. Court (Riker), 121 Nev. 225, 231, 112 P.3d 1070, 1074 (2005). Accordingly, we
ORDER the judgment of the district court AFFIRMED.
