Resolving upload errors

Encountering errors during the upload process can be frustrating. This guide will help you identify and resolve common upload issues to ensure your music is successfully distributed.

File-Related Errors

File Format Rejections

Error Message: "Invalid file format. Please upload WAV files only."

Solution:

• Convert your audio to WAV format (16-bit, 44.1kHz)
• Avoid MP3, AAC, FLAC, or other compressed formats
• Check if your export settings are correct in your DAW
• Re-export directly as WAV rather than converting

File Size Issues

Error Message: "File exceeds maximum size limit" or "File upload incomplete"

Solution:

• Ensure each file is under 2GB
• For very long recordings, consider splitting into parts
• Check your internet connection stability
• Try uploading files individually rather than in batch

Corrupt File Errors

Error Message: "File appears to be corrupted" or "Unable to process audio file"

Solution:

• Re-export the file from your original project

• Check your storage media for corruption

• Try using a different computer or browser

• Export with different settings (e.g., without dithering)

  Artwork Format Issues

  Error Message: "Cover art must be JPG/PNG, 3000x3000 pixels"

  Solution:

  • Resize artwork to exactly 3000x3000 pixels
  • Save as JPG or PNG format
  • Ensure file size is between 1.5MB and 25MB
  • Remove any layers or transparency

  Metadata Errors

  Missing Required Fields

  Error Message: "Required fields missing: [field names]"

  Solution:

  • Complete all required fields marked with an asterisk
  • Check for invisible spaces in text fields
  • Ensure all contributors have roles assigned
  • Verify release date is valid and in the future

  Invalid Characters

  Error Message: "Invalid characters detected in [field name]"

  Solution:

  • Remove special characters, emojis, or symbols
  • Check for hidden formatting or non-breaking spaces
  • Use only standard characters (A-Z, 0-9, basic punctuation)
  • Avoid unusual formatting like ALL CAPS or excessive punctuation

  UPC/ISRC Errors

  Error Message: "Invalid UPC format" or "ISRC code already in use"

  Solution:

  • Ensure UPC is 12-13 digits with no spaces or dashes
  • Verify ISRC follows correct format (XX-XXX-XX-XXXXX)
  • Check if you've previously used these codes
  • Let SeemDistro generate new codes if you don't have valid ones

  Connection and Browser Errors

  Upload Timeout

  Error Message: "Upload timed out" or "Connection lost during upload"

  Solution:

  • Use a stable internet connection (wired if possible)
  • Try uploading during off-peak hours
  • Upload files individually rather than in batch
  • Close other bandwidth-heavy applications

  Browser Compatibility Issues

  Error Message: "Your browser is not supported" or various display errors

  Solution:

  • Use the latest version of Chrome, Firefox, Safari, or Edge
  • Clear your browser cache and cookies
  • Try disabling browser extensions
  • Use incognito/private browsing mode as a test

  Session Timeout

  Error Message: "Your session has expired" or "Please log in again"

  Solution:

  • Log back in and resume where you left off
  • Complete uploads in one session when possible
  • Save progress frequently
  • Keep the tab active during uploads
