Getting error when trying to sync to Audio.com cloud

I am a new user to Audacity. I was trying to save my project to the cloud on Audio.com this worked beautifully the first time I used it. But every time since then when I have tried to save to the cloud I will get this error message. I have tried clicking on the ‘Save this project’ but the message will just pop up again. I then went into Audio.com and deleted what I had to hopefully reupload the newer version. However, the same message keeps popping up. I don’t know what I need to do differently.
