Message: Unexpected server response (0)

Hello, I’m suddenly getting Message: Unexpected server response (0)
but only when the page loads. When I click to view fullscreen, it pulls up the pdf just fine.
I don’t think related to site being in a RTL language because it was working fine before.

PDF.js v1.4.20 (build: b15f335)
Message: Unexpected server response (0) while retrieving PDF “https://farsihealthadvice.com/medical_articles_iranians_persians/wp-content/uploads/2020/10/Guide-to-quitting-smoking-in-Persian-Farsi-language-%D8%B1%D8%A7%D9%87%D9%86%D9%85%D8%A7%DB%8C-%D8%AA%D8%B1%DA%A9-%D8%B3%DB%8C%DA%AF%D8%A7%D8%B1-%D8%A8%D9%87-%D8%B2%D8%A8%D8%A7%D9%86-%D9%81%D8%A7%D8%B1%D8%B3%DB%8C-%D9%81%D8%A7%D8%B1%D8%B3%DB%8C.pdf”.
