521 error, development mode on, all fine


why cloudflare tells me, that my server is down, when i go in development mode all is fine.
so it is a cloudflare problem, right?


I’d guess it’s a caching issue: Try to Purge Everything from the cache page. And clear your browser cache.

I would also try a global test to see if it’s a limited problem:

Otherwise, it’s a mystery to me and you should open a ticket: support AT cloudflare DOT com


thanks i’m checking!
