Failures during uploading are generally because of a temporary server error. If your upload is failing then we would suggest trying the following:
- clear your browser history, cookies and cache
- use a different browser
- encode the file at a lower bitrate or split the file into multiple parts if it's over an hour's worth of content
- upload the file as an .mp3 instead
If none of the above suggestions have helped then please contact us, making sure you include as much information as possible about your problem (screenshots, details about your browser, step-by-step description etc.)
