Trying to connect to GHL Connect app

[Yellow Fin]

Hello,

Rooky question. I bought a second hand profilux 3.1 ex. Device is as new, and very complete
I try to make connection with GHL connect app. I always get a message that it is not possible. (Screenshot attached).
What data do i have to enter in screen (screenshot attached), to make connection. I already attached the divice to my computer and it was possible to connect to control center, i updated to latest firmware.
Can anyone tell what extention is on the right with the antenna? Haven't seen it amongst the profilux extention cards.
