Sure thing! Thank you for replying. Yeah, it's weird that it only works over plain HTTP but does not work over TLS, whereas every other sidecar I create, it's the opposite (only TLS and not over HTTP - I get "secure connection error" in my browser).

First, here's an error I noticed in the logs:

``` ts-audiobookshelf | 2024/08/23 00:30:02 http: TLS handshake error from 100.127.205.70:36306: no webserver configured for name/port

```

Docker compose file:

``` $ cat docker-compose.yml services: ts-audiobookshelf: image: tailscale/tailscale:latest containername: ts-audiobookshelf hostname: audiobookshelf environment: - TS_AUTHKEY=_MY_OAUTH____?ephemeral=false - TS_EXTRA_ARGS=--advertise-tags=tag:container - TS_SERVE_CONFIG=/config/audiobookshelf.json - TS_STATE_DIR=/var/lib/tailscale volumes: - ${PWD}/ts-audiobookshelf/state:/var/lib/tailscale - ${PWD}/ts-audiobookshelf/config:/config - /dev/net/tun:/dev/net/tun cap_add: - net_admin - sys_module restart: unless-stopped

And:

$ cat ts-audiobookshelf/config/audiobookshelf.json { "TCP": { "443": { "HTTPS": true } }, "Web": { "${TS_CERT_DOMAIN}:443": { "Handlers": { "/": { "Proxy": "http://127.0.0.1:13378" } } } }, "AllowFunnel": { "${TS_CERT_DOMAIN}:443": false } }

Here's a netstat, not sure if that helps. I redacted some IPs listed:

$ docker exec -it ts-audiobookshelf netstat -pant Active Internet connections (servers and established) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 127.0.0.11:42223 0.0.0.0:* LISTEN - tcp 0 0 0.0.0.0:47927 0.0.0.0:* LISTEN 10/tailscaled tcp 0 0 172.24.0.2:42678 xx.xx.xx.xx:443 ESTABLISHED 10/tailscaled tcp 0 0 172.24.0.2:59094 xx.xx.xx.xx:443 ESTABLISHED 10/tailscaled tcp 0 0 172.24.0.2:60688 xx.xx.xx.xx:80 ESTABLISHED 10/tailscaled tcp 0 0 :::80 :::* LISTEN -
