from the LED indications , your the connection to your modem is established.

have you tried checking the unifi credential on the router page?

i've the same wifi router.

edit: just saw the photo link, now i suspect there may be issues with your fiber cable?

you can also try checking the fiber termination box (the small white box) before the modem just to ensure the fibre is plugged in properly...sometime you may never know the connection may have been a little loose and when you do some cleaning, it might have disconnected it..
