I looked at your crypto isakmp output and it seems to me the problem may reside in IKE policy so phase-1 complets but re-stars again in a second atempt which fails , I suggest both ends do check within the IKE policies encryption algorythm settings e.i hash, aes-256, dh group types , in other words anything to do with IKE policy do match at each end. Can you confirm the other end do agree with your IKE settings?
