When you encounter error messages while uploading files on OmniStor for Web, it is recommended to check the following steps to troubleshoot the issue.

1. Storage Space is Full: Insufficient available storage space in your account will prevent file uploads. You can: go to "Account Settings > Account Information" to check the remaining space. If you need to increase space, please contact the system administrator.
2. File Size Exceeds Limit: If the uploaded file exceeds the single file size limit set by the system administrator, the upload will fail. You can go to "Account Settings > Account Information" to check the file size limit.
3. File Format Not Allowed: Please check whether the file format is among the system-blocked types. If it is a restricted file format, the upload will not be allowed. (For information regarding system restrictions and blocking of file types and formats, please contact your system administrator for confirmation.)
4. Insufficient Permissions: If you are uploading files to a folder shared by others and do not have "edit" permissions, you will not be able to upload. In this case, please contact the folder owner to confirm the permission settings.
5. Network Connection Issues: Connection interruptions or instability during the upload process may cause the upload to fail. If this occurs, please ensure your network connection is stable and try uploading again.
6. Unknown Errors: If an unidentifiable system error occurs, it may cause the upload to fail.
   • In this case, you can try uploading again. If the problem persists, please contact the system administrator for assistance.
