Domain not authorized after 24 hours?

Hi, 

I was able to embed a PDF into my website just fine but after the weekend it is saying the application domain is not authorized. Not sure why it worked on Friday but checking back on Monday it is no longer authorized? Am I missing something?

API KEY (CLIENT ID)
0a71ae70d269413e899f7116c18a5609

ALLOWED DOMAIN

Thanks!
