The wifi library 2.16 added esp_wifi_set_protocol, but did not check if protocol was not NULL.
The captive-portal-wifi-setup is not aware of this new feature and does not set the protocol field of struct mgos_config_wifi_sta.

Update mos to latest and it will be ok.


Wonderful! thanks @nliviu. You solved my problem!
