Error building with cloudflare dns and xcaddy (i/o timeout)

[Austin-s-h]

Hi and thanks for helping to maintain an awesome service! I have been running into some issues building caddy with cloudflare dns enabled. I've set up my Dockerfile for caddy and I'm running it from a docker-compose yaml. This might be related to #11 , but the actual error is different and pinning the latest versions fails. I'll also try specifically with 2.2

FROM caddy:2.6.2-builder AS builder

RUN xcaddy build master --with github.com/caddy-dns/cloudflare@latest

FROM caddy:2.6.2

COPY --from=builder /usr/bin/caddy /usr/bin/caddy

I believe this might actually have to do with the reference of the github repo. It's looking for https://github.com/caddyserver/caddy/v2 but the actual caddyserver repo has been renamed to https://github.com/caddyserver/caddy/

doh, its missing as a module when you try to download it from caddyserver too. I came here to try to just build it myself. So I assume the caddyserver.com infrastructure also cannot build it properly.

Not sure what the issue is -- works for me; but just in case I tried updating dependencies in case that helps. (go.mod)
