Error: Connection Failure When Uploading Remote PDF URLs

[Virgarg7]

Issue Summary:
When attempting to upload and parse remote PDF URLs using our current backend implementation, the process fails with a connection error. This issue occurs despite the successful parsing of locally uploaded PDF files.

Expected Behavior:
The backend should successfully fetch the PDF from the remote URL, parse its content, and return the extracted text to the frontend.

Actual Behavior:
The backend fails to fetch the PDF from the remote URL, resulting in a connection error. This error does not occur with locally uploaded PDF files.

@Virgarg7, it would be more helpful if you could share the code snippet that you have implemented to parse uploaded/fetched pdf.
