Hi @amjadgul05,
You’ll need to allow access on the port. If you are using only IPtables, Digital Ocean have a pretty good article about how to do it - ARTICLE
If you have installed csf for instance, you can allow the mentioned port in the configuration file
/etc/csf/csf.conf
and then
TCP_OUT = some port, some port, 547, some port
I hope the above helps,
Kind regards, Kalin
