I'm running a traefik behind the newt tunnel.

On my traefik behind the newt tunnel i get the following errors:
2025-02-15T16:05:16+01:00 DBG log/log.go:245 > http: TLS handshake error from 172.16.100.1:44880: tls: no certificates configured
2025-02-15T16:05:17+01:00 DBG github.com/traefik/traefik/v3/pkg/tls/tlsmanager.go:216 > TLS: strict SNI enabled - No certificate found for domain: "", closing connection

It seams that pangolin ist not forwading the https host header.

As my traefik is configured for SNI and needs the hostname to decide to which backend the traffic needs to be send.
Other services behind the newt tunnel without SNI are working.
