It originally didn't load for me on Firefox. I turned my ad blocker off though and it loaded.

Thanks for catching that! I couldn't find anything from my logs, that was frustrating. The frontend of Peerdiem is served from www.peerdiem.com while the backend uses www.api.peerdiem.com. It seems that a strict tuning of the AdBlocker might prevent requests to a subdomains. I will put up an explanatory text on the homepage for those encountering the same issue. Thanks again!

Yep, Firefox with ad blocker here too. That seems to be the issue

I'm not sure it's a browser issue, maybe a load issue? Could there be throttling on the backend API you're using to fetch the artwork?

Do you get the same "No painting found for today" error as well? I'm fetching the artwork + metadata myself in advance to avoid any throttling on the API. I don't see any error on that endpoint in my logs, this is strange. I will investigate it further.
