Transport and Curl errors for Personal FTP Repository setting

[MarknLA]

When I try to reset the Personal FTP Repository setting in Backup Manager, I get "Transport error: unable to list directory: Curl error: Failure when receiving data from the peer"

I've read a solution to this issue for Plesk for Linux, but not for Windows. I have my FTP server setup for FTPS (require explicit FTP over TLS) and when I put the correct information in each box, I get this error. In the meantime, the current settings (for standard FTP) are incorrect.

Obviously the most important this is to correct the Transport and Curl errors, but if I'm unable to do so, how do you clear the current setting? There doesn't seem to be a way to do it...

I was finally able to set the Personal FTP Repository with the correct settings. However, when a backup job is initiated it still errors out. Looking at the backup.log, it appears it has something to do with the hostname not being in the DNS cache. Anyone know what this means?

Here is an excerpt from backup.log:

[2014-10-10 17:03:39.576|5584] Debug: * Closing connection 0

So, I guess it's trying to send the data to a local IP instead of the hostname's IP (I changed the hostname's actual IP in the log excerpt above to xxx.xxx.xxx.xxx), as well as the FTP server name (ftp.servername.com).

I was wondering where it got the local IP address, but then I looked above in the log and it had this for the server certificate:

[2014-10-10 17:03:39.570|5584] Debug: * Server certificate:

[2014-10-10 17:03:39.571|5584] Debug: *      SSL certificate verify result: self signed certificate (18), continuing anyway.

Anyone have any thoughts on this?

As per the error server is failing to connect to ftp server on port 21. Can you check id port connectivity is working between both servers.
You can simply run command telnet ftpserverip 21
