Sophos AP15c Permanent orange light

Good day,

I’m busy with a firewall upgrade at a client form a Sophos XG85 to a XG86. After installing the XG86 the AP15c shows an inactive. For an easy setup I backed up the XG85 and restored it to the XG86. Everything works fine except for the AP15C. I shows a s inactive on the wireless access point profile setup on the XG86. I tried to reset the AP15c but the light on the AP does not change. It is in a constant orange state does not matter what I do. I tried to flush the AP using the Sophos flush tool but can’t connect to the device at all, even with a coms cable. Please help
