Why the USG trunk profile cannot work as expect, the traffic always went to wrong interface?

Please check policy route rule trunk profile status, dead or alive.
The status depends on Interface “Connectivity Check”,  what if you set up an improper host to perform connectivity Check, it always in dead status, that why the traffic always go to wan 2.
Try to adjust a suitable one as “connectivity check” host and try it again.
