Export to csv or pdf error

when i try to export, i get blob:https://mydomain.org/e7a01512-3ea1-413c-a3be-8c0b5855329f
and a screen with the table instead of exporting the file.

That means you have server side error, you may Check HTTP Response.

No response in concole only this on the screen when i export to PDF .
%PDF-1.7 1 0 obj... (omitted) ... 13775 %%EOF

That is the binary data of the PDF file. You may Check HTTP response again and see if the content type of the response is “application/pdf”, it should be. If it is, your browser cannot handle PDF (most browsers should be able to, are you using some less common browser?), make sure you use a browser that can view PDF.

I am using Chrome . This happens only on remote server ,works well on local. The host dont seem to understand whats going on.

Check the configuration of the web server of your hosting server, make sure the non-HTML content types such as “application/pdf” and “text/csv” are allowed.
