Issue Can't redirect to the updates

[Brian Young]

Server operating system version

CentOS 7.4

Plesk version and microupdate number

18.0.49

Hello, community.

I need the urgent help.

I am going to change the php version to latest, but I can't find new version.



So I am going to update the php via the plesk's updates.
But I can get the "ERR_CONNECTION_TIMED_OUT", and can't redirect to the updates page.



I appreciate for solving this issue.
Thanks in advance.

You need to make sure that port 8447 is open
1) in Plesk firewall
2) at the data center's firewall for your server

Thanks for your quick reply.

I've executed the command " iptables -nL | grep 8447"

So got the following result.

Accept tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:8447

Is it wrong?
