Metrocluster - error on lif placement

[hazy vortex]

Hi all,
Installed a new MCC-IP, configured many SVMs, all work great except 4.
I receive the following message:
Discovery of LIF with address 10.157.65.98 failed from destination cluster Ensure that the destination cluster has ports that have connectivity to the LIF on the source cluster.
Lifs:
svm1
lif_svm1_nfs up/up 10.157.65.98/24 fi100780-02 a0c-105 true
svm1-mc
lif_svm1_nfs up/down 10.157.65.98/24 fi100380-02 a0c-105 true
ifgrp are all good and the same.
Walked through: https://kb.netapp.com/on-prem/ontap/mc/MC-KBs/LIF_interface_of_SVM_is_inconsistent_between_MetroCluster_sites
No result.
Also used: https://kb.netapp.com/on-prem/ontap/mc/MC-KBs/Discovery_of_LIF_with_address_IP_Address_fails_from_the_destination_cluster
No result.
Waiting for network to confirm ARP flooding is enabled.

Thanks!

make sure the two VLANs (105) are indeed connected to each other, and are letting ARP packets through (sometimes, firewalls filter those out)

you can test it e.g. by creating a temporary SVM on the MC side, giving it an IP address in the 105 VLAN, and trying to ping it from the other cluster's SVM

Thanks, will try!
