I’ve been using Cloudflare as an external DNS provider for a kubernetes cluster. A test application that I threw together has been working for the past week or so and hasn’t stopped at all, but all of a sudden the A record for the domain can no longer resolve despite the proper IP still being in my Cloudflare dashboard. I thought maybe it was some crazy local problem, but checked the records via MX Toolbox and still don’t see the records.
➜ ~ dig NS nanosleep.cloud +short @22.214.171.124 norm.ns.cloudflare.com. roxy.ns.cloudflare.com. ➜ ~ dig ping.nanosleep.cloud +short @norm.ns.cloudflare.com # nothing returned :(
➜ ~ curl -H "Host: ping.nanosleep.cloud" https://126.96.36.199 -I -k HTTP/1.1 200 OK Server: nginx/1.17.8 Date: Tue, 28 Jul 2020 14:30:00 GMT Content-Type: text/html; charset=utf-8 Content-Length: 365 Connection: keep-alive Vary: Accept-Encoding Last-Modified: Sat, 25 Jul 2020 07:03:49 GMT Set-Cookie: _session=MTU5NTk0NjYwMHxEdi1CQkFFQ180SUFBUkFCRUFBQUtQLUNBQUVHYzNSeWFXNW5EQTBBQzE5ZmJHRnpkRjkxYzJWa0JXbHVkRFkwQkFZQV9MNUFiTkE9fEdrwpBMsELV5WAYHO-Dk0JUJswK80_38fxq3gvspuPi; Path=/; HttpOnly; Secure; SameSite=Lax Strict-Transport-Security: max-age=15724800; includeSubDomains
Not sure exactly what’s going on, but any help would be appreciated.
