change trojan port

[afshin1394]

Dear,
I need to modify trojan running port on my server but when I change it in config file located in "/usr/local/etc/trojan/config.json" and restart the trojan service it doesn't get change.
for instance I change remote-port : 80 to remote-port:2083 and then I restart trojan with:

systemctl restart trojan 
systemctl restart trojan-web

but the running port doesn't get change
can you please support

Update to the latest version, then use trojan port to change remote port.
