Remote access

Hi,
I’m trying to access my plex medi server remotely. on configuration of server it shows that I can access remotely but I can’t do it :frowning: , can someone help me please ?

My plex is on a home made freenas server, I’m connected on a orange 4G connexion passing through my RT-AC68U asus router.

Living in D.R.C.

Thanks in advance.
