I have two different FreePBX distro systems exhibiting the same issue.
System 1 = version 1.812.210.57-1
System 2 = version 1.817.210.58-1
Both systems are setup to backup via FTP and both systems successfully backup to the FTP server.
The problem I am having is that when I go to do a restore and select the server I want to restore from I do not get any files listed. I can log into the FTP server from a shell from system 1 & 2 and see the files.
When I try to list the files on the FTP server from the FreePBX GUI I get the following in freepbx_dbug log
