Local Tuya - can't add devices on TPlink access point

I had 4 smart plugs setup in Local Tuya and all were working. I replaced an old airport extreme 2 of these devices were on with a tplink ap, rediscovered in the Tuya app, registered in the cloud etc, got the new local keys. But now they fail to be added back in Local Tuya. It throws “An unknown error occurred. See log for details” Here’s the log:

Unexpected exception

EDIT - I configured the tplink ssid to be the same as the remaining wlan. Re discovered the two switches in tuya app and now local tual works.

What? Can you please elaborate?
