Hello

Here are a few steps you could try:

1. Rename the File Correctly : Try renaming the file manually to match the exact format as per your 10th certificate .

2. Check Allowed File Naming Conventions : Ensure there are no extra spaces, special characters or unsupported file extensions in the file name .

3. Contact Support : If the system still rejects the upload, reach out to the helpdesk or support team of the application portal for guidance .

4. Wait for Correction Window : If possible , complete the process as far as you can and wait for the correction window to make the necessary changes .

hope this helps you .
