Hello @Maiquel, welcome to the community.
Just so that I follow you when you remove the HA arrangement (i.e you have two separate MX450 in concentrator mode), the Auto-VPN over MPLS and internet for the Branch is up. When you put the MX450's into HA, the Auto-VPN works only over the MPLS connection?
Is this a correct assumption of your problem?
