The solution was : the port 443 was already in use
There was no warning from docker that it couldn't listen to the port. I tried to use another program to sniff my port 443 and check if I was receiving data, and it's only then I got the information the port was already in use.
For those interested, it was a vmware that was fully stopped, not allowed on startup, yet was still listening on 443..... not something I like
