Some APs reverting back to inform IP instead of the URL after a power outage

So I host two sites on my RPi unificontroller 5.12.35 (Build: atag_5.12.35_12979)
Sites are in the same building different vlans, pfsense router in between, DNS resolution of the inform URL tested and works.
One site with two APs (4.0.80.10875) Both AP’s a week ago were reset and readopted via URL and not IP (set-inform http:// FQDN:8080/inform) Adoption went well, did it twice as per instructions, AP’s were rebooted many times and always came back up. When I checked via SSH info I got: status: Connected (http:// FQDN:8080/inform)
Second site with one AP (4.0.80.10875) AP a week ago was reset and readopted via URL and not IP (set-inform http:// FQDN:8080/inform) Adoption went well, did it twice as per instructions, AP was rebooted many times and always came back up. When I checked SSH info I got: status: Connected (http:// FQDN:8080/inform)
Today I had a power outage, whole site was down for about 4 hours. When the power finally came back, both APs in the first site had their Status: Connected (http://192.168.1.1:8080/inform) instead of the URL.
The second site had status: Connected (http:// FQDN:8080/inform)

So I’m not sure why, does anyone have any ideas?

If anyone has some thoughts on this, I’d appreciate it.

Thank you.
