AirLift FeatherWing - ESP32 WiFi Connection issues

[Grayspace]

I'm using the AirLift FeatherWing - ESP32 WiFi Co-Processor together with the Feather M4 board and unable to connect to my home WiFi network. Working through this project: https://learn.adafruit.com/air-quality- ... et-connect and using its example code, as below:

I am able to see in serial that the board recognizes my network, yet fails to connect (see attached image). What will fix the connection? Is my router blocking, perhaps with a built-in security setting? It is a TP-Link Archer C20 AC750 wireless dual band router, brand new. Sorry I'm new to this.

The RSSI (signal strength) looks fine for the circled AP in the scan. But the exception refers to an SSID that is not in the scanned list. The two circled APs are different SSIDs. SSID is distinct from a hostname you may see in your router.
