Connecting Blink XT2 sync module to USG

I am having trouble with using the blink XT2 and a unifi USG.
i think the blink module is being block somehow by the unifi router.

should i open any ports to allow it to communicate?

how would i test if its being blocked.

Hi, did you solve the problem?
It seems like my unifi System threw the blink module out and won’t let it back in.
Tried several things that didn’t work. Maybe there is something in the settings that I need to change?
