Wifi logging with lilygo

i tried to login with
Open MQTTGateway_lilygo_rtl_433_ESP

opengate mqtt gives after flashing on the screen:
W1FOMG_lilygo_rtl_433_ESP

but
not any answer or possibility to login
The good is:
network gives: OMG_lilygo_rtl_433_ESP
but no credential key is present.
that is why i want to renew the whole procedure??

so i cannot give my secrets to create something
Who can gives me advice
