I have half dozen sites, mostly small blogs etc… I was running them on scaleway and doing CDN and DNS routing using cloudflare happily for a long time. Today I suddenly start to get 522 errors on cloudflare which is basically cloudflare can’t get response from my server. Everything works fine and when I disable cloudflare routing and connect to my server directly, everything works. Seems my server’s network is rejecting connections from cloudflares all the sudden. I suspect scaleway may temporarily or permanently banned cloudflare ips.
Does anyone know if I can request scaleway to whitelist cloudflare ips in terms of incoming traffic to my server?
