TP-Link AX6000 router on 2.4Ghz [5Ghz turned off]. Tapo app Ver:3.1 on Samsung S21 Plus android 13.

Light is about 0.5M from router and so is my phone.

I log on to Tapo app, select a room, add a device, select lights, then L530, turn on the light when the says so, light begins to blink.

The app then says it will use a temporary wifi network to connect to Tapo_Bulb_BD99. I'm then told this network is not connected to the internet???

Then the app says it's connecting and the bulb slides into the phone image on the screen and goes to my 2.4ghz logon screen. I logon and the app goes to 'pairing your Tapo device . . ' for a long time. after about 30 seconds? the L530B blinks a few times and the app on my phone still says it's paring my Tapo device. . . 

Then after about a minute, it says 'Pairing Failed'.

I have now tried this 5 times with no success.

Please help me make these lights work.
