[go-nuts] strange stack trace when panic

Hi, I'm confused by the stack trace when panic, and I have searched both in history topics and google. If I use panic, the stack is fine, code is https://play.golang.org/p/Yb7fYW9ro3 , output is: panic: Panic from user goroutine 1 [running]: main.causedPanic() /tmp/sandbox078566511/ma

Re: [go-nuts] letsencrypt, localhost and autocert

What it boils down to is that your server tries to get a certificate for whatever name is in the URL. But Let’s Encrypt won’t issue a certificate for localhost, for various reasons—not the least of which is that a certificate for localhost makes as much sense as having a photo ID that says “Me”

tl;dr: You need a) a publicly routed IP address (either IPv4 or IPv6 is fine), b) a publicly resolvable domain that points to that IP address and c) actually point your client (browser) to that domain. Long explanation: The HTTP client will use SNI to tell the server the domain it needs a cert fo
