Resolved Add/remove component bug on access

[Pascal_Netenvie]

Hi,
On new server under Debian 9 and Plesk 17.8.11 i try to access Add/Remove component in Plesk Installer but it run endlessly and never display the screen ...
Or i have an error message from browser saying page take too long to display ...

Is there some problems with Debian 9 ?

Some idea ?

Make sure that port 8447 is not firewalled there.

Strange cause i see Installer and he run under port 8447 too.
Whatever i added a rule for port 8447 in firewall and now it run ok.

Thanks.
