This worked up until last week. I have verified the login credentials via filezilla, which works perfectly. I have also contacted my web host, and they have said that the error that they see on their end is that Lightroom is using an outdated sftp protocol, which is no longer considered secure, and is no longer supported on their server.


The sftp requirements for my host are listed here:


I am running the latest version of lightroom classic CC. I appreciate your help in getting this issue resolved quickly. I have also try deleting the preset and making a new one with no change. Thank you.

There were some under the hood changes in Lightroom 7.5, released earlier today. Please install it, and see if you have the same FTP issues. Let me know if you do and I can raise a bug with the team.
