Unexpected server response (206)

Greetings,

I recently bought the premium version of pdf embedder.

Most of my pages use the pdf embedder for pdfs. Sometimes, not all the time, a page will display the error, “Unexpected server response (206) while retrieving PDF” for each embedded pdf that doesn’t load.

This will go away when the page is refreshed and the embedded pdfs will display after the page is refreshed. However, I can’t have outside parties seeing this message when they first click on the page. It’s variable when the pdfs decide not to load and display this message. Sometimes they load fine.

Any response is greatly appreciated. I am hoping to resolve this issue quickly and I thank you very much for your help.
