Amazon SFTP and Publishing

I have a site I’m trying to use the built-in “publish” to upload to Amazon AWS using SFTP. I’ve confirmed the same password and SFTP server using Filezilla and it connects fine via SFTP. I get an
error in sparkle using the same credentials with SFTP selected and the proper key.

Is Sparkle 3.0 SFTP implementation not compatible with Amazon SFTP?

I don’t know that there’s different SFTP implementations. Is the problem with the key or is it a connection issue?

It looks to be a connection issue. I get the “FTP server is not correct or blocked”. I’m using the same FTP
address and transfer key file I use in filezilla. I’ve also tried it in both Filezilla and cyberduck and they both connect fine with the same address and info.

Thanks

Probably best if you get in touch. feedback@sparkleapp.com
