Description (partial)

No matter which Interface on Service Side VPN is used, the result is the same when trying to run a Simulate flow for tunnel and Service Path. Below, the error that we got:

Failed to run tunnel path
Interface GigabitEthernet0/0/2 not up

Failed to run service path
Interface GigabitEthernet0/0/2 not up

VPN -> 10 (Service side)
Source Interface -> GigabitEthernet0/0/2
Source IP -> ************* (I hide intentionally the customer IPs)
Destination IP -> ************** (I hide intentionally the customer IPs)
Protocol -> 1

it's worth saying that:
1.- Interface is up and running
VPN 10 - Interface GigabitEthernet0/0/2 - Admin Status UP - Operational Status UP

2.- There is full IP connectivity back and forth
