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
