Troubleshooting: “Service Unavailable” message

If you see a “Service Unavailable” message after selecting Submit, it is likely  due to an issue with the file you are uploading, such as an unsupported format or a corrupted document. This error is not related to your account or the submit documents service.

What this error means

This error can occur when the file you’re trying to upload is either corrupted or saved in a format our system doesn’t accept, even if the filename and extension appear to be correct.

How to fix the issue

Option 1: PDF

• Open your document and select save as a PDF or print to PDF.
• Upload the new PDF file.

Option 2: Picture

• If printing to PDF doesn’t work, take a screenshot or picture of your document and save it as a JPG or other image file.
• Upload the image.

Option 3: Word document

• Alternatively, you can paste a screenshot of your document into a Word document.
• Save and upload the Word document.
