Hi rugfoot ,
This mostly happen when there is something wrong with the FTP server settings in Lightroom.
Please check them and try again.
Are you able to connect and upload using a different FTP Client?
Also try the steps below:-
1. From the Web module in Lightroom, click Export instead of Upload.
2. Save the gallery to a location you can find easily (like your desktop).
3. Manually copy the gallery from its saved location to your FTP server.
Let us know if that helps.
Thanks for replying Akash. I think the failed uploads are more due to internet problems. But it's not so much that issue that I want to fix, I just want to know which files didn't upload, so I can upload them again. Apart from the initial error message, is there any other way of knowing? Thanks.
OK, thanks, Akash, yes that looks like it.
