This seems similar to this thread, so I’m guessing it might be again an issue at the Cloudflare side.
When visiting pixabay all requests work just fine, except one of the css file https://pixabay.com/static/css/min/base.0fafb922.min.css hosted by cloudflare, which returns status 530 (error 1016 of CF)
I’m in China, but all other URLs within the domain pixabay are OK. If I fire up an VPN, the css file can be retrieved.
Any ideas?
