tailscale-proxy fails with TLS

[jamie-at-arkifi]

When you use tailscale-proxy with HTTPS/TLS, it tries to start QUIC and then fails:

This is from inside a container:

ARG CADDY_VERSION=latest

FROM docker.io/library/caddy:builder AS build
ENV XCADDY_SKIP_CLEANUP=1
RUN xcaddy build \
    --with github.com/tailscale/caddy-tailscale \
    $CADDY_VERSION

FROM docker.io/library/caddy
COPY --from=build /usr/bin/caddy /usr/bin/caddy

Using the command ['/usr/bin/caddy', 'tailscale-proxy', '--from', 'tailscale/myhost:443', '--to', 'backend:7071']

Downgrading to Caddy v2.6.4 does not resolve the issue.

I have the same issue.
