OCRSpace Free - Error 99

I’m trying to convert a PDF using the OCRSPACE FREE API, and I’m getting the error

“OCRExitCode”:99,“IsErroredOnProcessing”:true,“ErrorMessage”:[“Unable to process the file. Please check if the file has sufficient permissions and allows access and is not corrupt.”],“ProcessingTimeInMilliseconds”:“19859”}"

What can it be?

I guess the free OCR API was overloaded. Does it work again meanwhile? All is fine according to https://status.ocr.space/

The free API and the PRO API run on different servers in different datacenters.

Hy,

Yes, now the API is working correctly.
Thanks for the return.
