My Upload Is Stuck or Failed

On iOS and Android, close Vandall and open it again. The queue is saved on your device, so everything unfinished, including anything that failed, starts again once you are signed in. On the web there is no saved queue, so keep the tab open until the upload finishes. While the app stays open, a failed file waits for you and nothing retries it on its own. Give a slow connection a few minutes before you decide it is stuck.

Check that the file is a supported format: WAV, FLAC, MP3 or AIFF for audio, PNG or JPG for cover art, and PDF for documents. A file in an unsupported codec (such as M4A lossless), or artwork over the size limit, fails without an error message. Convert it to a supported format, then try again.

Move to Wi-Fi before uploading several large files. A 24-bit 48kHz stereo WAV of a 4-minute song is roughly 70MB, and uploads fail most often when several files go over mobile data. If four stems are stuck, switch to Wi-Fi and select them again. That almost always fixes it.

Look for the red pill with a warning sign at the top of the track. It names the file that failed. Tap ⋮ at the right of the pill, and you'll see Retry, Remove and Cancel. Tap Retry to send that file again. Files from the same batch that already uploaded stay where they are, so you never re-send the whole selection.

If the same file fails three times on a stable connection, contact support. Send the file, the track name, and your device and operating system. This is rare. Almost every stuck upload comes down to the connection or the file format.
