APX-120 Access Point Show inactive on XGS116

In the beginning, APX-120 access points were managed using SOPHOS CENTRAL.

Now I want using xgs116 firewall to manage. After I accept the access point from the pending list

As title says, it stays in inactive Access points. And it seems I can't control the access point either.  How do I solve this problem?

I searched for many articles in the community, no related solution articles found
