Problem with FXServer (Linux)

Hello,

I have a big problem with every servers I’m trying to make (tried different dedicated machines).
When I finish installing my server, I can clearly see my server but only in the direct connect when I put the IP, but first I see that the gamemode is “Freeroam” and the map name is “Map name” and when I’m trying to connect to my server, I am stuck at the message “Obtaining Steam Ticket”.

Here is my server.cfg

# you probably don't want to change these!
# only change them if you're using a server with multiple network interfaces
endpoint_add_tcp "0.0.0.0:30120"
endpoint_add_udp "0.0.0.0:30120"

# MySql section
set es_enableCustomData 1
set mysql_connection_string "server=**private**;database=**private**;userid=**private**;password=**private**"

#### FIVEM DEFAULT ####
start mapmanager
start chat
start spawnmanager
start sessionmanager
start fivem
start hardcap
start ■■■■■■■
start scoreboard
start baseevents

start essentialmode
start esplugin_mysql
start es_admin2

#### ESX MENU ####

# a comma-separated list of tags for your server
# for example: sets tags "drifting, cars, racing" or sets tags "roleplay, military, tanks"
sets tags "default"

# set an optional server info and connecting banner image url.
# size doesn't matter, any banner sized image will be fine.
#sets banner_detail "http://url.to/image.png"
#sets banner_connecting "http://url.to/image.png"

sv_hostname "My New Server?!?!»"

# nested configs!

# loading a server icon (96x96 PNG file)

# convars for use from script

# disable announcing? clear out the master by uncommenting this (your server will not be listed in the serverlist if you uncomment this!)
#sv_master1 ""

# want to only allow players authenticated with a third-party provider like Steam (don't forget, Social Club is a third party probvider too!)?
#sv_authMaxVariance 1
#sv_authMinTrust 5

# add system admins

add_ace resource.essentialmode command.add_ace allow add_ace resource.essentialmode command.add_principal allow

# remove the # to hide player endpoints in external log output
sv_endpointprivacy true

# server slots limit (must be between 1 and 31)
