Resolved FTP error retreiving directory list

[Cordal]

In a system with Debian 8, after updating Plesk Onix to Plex Obsidian, we observe that when an ftp connection is made to any subscription, it is done without problems, but when it is retrieving the directory listing it takes too much time and throws the following mistakes:

error: Connection timed out after 20 seconds of inactivity
error: Error retrieving directory listing

We do not know what may be due, nothing has been touched in the configuration simply updated to Obsidian and from that moment the aforementioned error occurs.

Any suggestions?

Looks like an issue with firewall + passive FTP port configuration. Have a look here:

Thanks for your answer.

The connection to the ftp server is done without problems, the problem comes when you are trying to retrieve the directory listing, which is sometimes done without problems, but most of the time it gives the following errors:

error: Connection timed out after 20 seconds of inactivity
error: Error retrieving directory listing

Yes, these are exactly the symptoms of passive mode + firewall problems. The FTP protocol is using a separate TCP connection for data transfer (including directory listing).
If you did not configure your passive ports correctly and you did not activate the FTP connection tracking module in your firewall, then you will have problems.

Did you follow the steps mentioned in the 2 links I posted?

It's a firewall problem

Try connecting without SSL and see if the directory listing (and or up/downloading) works then.
Also make sure that you are using a passive FTP connection.

If it works, then you need to check/configure the passive ports for FTP on your ftp server as well as your firewall.

a) check/adjust passive ftp port range in the file /etc/proftpd.d/55-passive-ports.conf
b) open all these ports on your firewall for incoming TCP connections


please also make sure, that the nf_conntrack_ftp module is loaded and - depending on the OS you're using - the net.netfilter.nf_conntrack_helper sysctl value is enabled.

Thanks for the answers, the problem was solved by following the instructions in:

Hello All. I know it is already resolved, but the best way to get the issue fixed is to allow ports 21 and 49152-65535, and it should work. I used FileZilla.

Thank you all for your comments!
