Remote Peer Configuration: In the header section of the received Hello packet, the field AuType is listed as 0 (Null/No authentication), while the error message indicates a mismatch. This means the remote peer (0.0.0.112) sent a Hello packet with no authentication (AuType 0), whereas the local Fortigate receiving the packet expects OSPF cleartext (AuType 1) or MD5 (AuType 2) authentication, or vice versa—meaning the remote peer is sending authentication (cleartext/MD5) while the local side expects none, or the remote sent cleartext/MD5 (AuType 1 or 2) and the local side has none or a different type configured (Option A).

Remote peer (0.0.0.112) send null (no authentication) in hello packet, and local FGT debug shows "auth type mistmach"; so local FGT expects Cleartext (autype 1) or MD5 (autype 2).
