I have purchased the SFTP add-on and installed it on a test site. The hosting environment is shared hosting with a large provider. Our IT department has setup an FTP server for us to send the backups to. I have been able to connect to it using a separate FTP client.
After getting the backup plugin setup on the test site and entering the SFTP credentials, I got the following error.
`
SFTP settings test result: Failed SSH 2 login failed.
Messages: PHP event: code E_USER_NOTICE: Cannot connect to sftp://ftp.xxxxxxx.com:22 Error 1071327460. Unable to find the socket transport “sftp” – did you forget to enable it when you configured PHP? (line 1187, xxxxxxxxxxxxxxxx/SSH2.php)
I spent some time with our web host to find a solution for the problem. After working with them for some time, they said we need to work with the plugin author to figure out what the problem is. They cannot offer any additional help without more information.
I contacted our IT department and they have checked the error logs on the FTP server. There are no entries for the connections I have tried to make. Therefore, we can assume the process stops at the web host.
I reviewed your forum and found several posts about people having the same issue. The solutions seem to range from connecting without SSL to changing firewall settings on the FTP server. I couldn’t find an answer that made enough sense to me to try.
What is the solution?
