Livebox

Hello I am french
I have a live box (sorry my english is poor, it is my "router"
My ESP is connected to my live box
I am sure that my code is clean
I want my ESP to send an http address on the web
It look like https://maker.ifttt.com/trigger/capteuractive/with/key/xxxxxxxxxxxxxx
I have hidden here the key.
It worked fine but i crashed my live box and lost all my parameters inside
I don't know how to parameter my livebox
in the code i have these instructions :
const int httpsPort = 443

how can i configure my live box ? not it don't work
Thanks

I have a live box

I'm missing a link to that "live box"!
I guess that's a device but we have no clue what device it is. It's your job to provide the necessary information!
