Recently, my site went down spontaneously. I believe the SSL certificate expired, and when Caddy tried to renew, the renewal failed.
When I a manually started up caddy (by running
caddy with no arguments in the directory with the
Caddyfile), I got the following output:
Activating privacy features...2017/11/11 21:58:43 too many renewal attempts; last error: acme: Error 400 - urn:acme:error:connection - DNS problem: NXDOMAIN looking up A for www.arjun-menon.com Error Detail: Validation for www.arjun-menon.com:80 Resolved to: Used:
After that, I went to my registrar (Namecheap)'s website, to revisit the configuration of my domain. I noticed that DNSSEC was turned on, so I turned it off. After waiting for a few minutes, I ran
caddy, but got the same error shown above.
After re-running Caddy a few times, I hit an ACME rate limit for errors, and get this now:
Activating privacy features...2017/11/11 22:12:07 too many renewal attempts; last error: acme: Error 429 - urn:acme:error:rateLimited - Error creating new authz :: Too many failed authorizations recently.
caddy -version is
Caddy 0.10.10 (non-commercial use only).
So I can’t debug this anymore, and try to figure out what’s wrong. So I thought I’d give you guys a shout. Anyone experienced anything like this?
