<![CDATA[Can't use localtunnel properly with app proxy]]>Hi there,
I'm trying to install localtunnel server in order to share my local stuffs to the world.
I have localtunnel server working properly on port 4000 on my server, using docker (I just changed the port to 4000).

I use an app proxy to be able to contact this service from outside :
Screenshot 2024-01-31 at 16.26.27.png

With ssh in my server I got this :

$ curl http://localhost:4000/api/status
{"tunnels":0,"mem":{"rss":59826176,"heapTotal":33873920,"heapUsed":20766296,"external":699069}}

But when I try to call it from outside of the server, I got this :

$ curl https://app.[mynameserver]/api/status
404

Can you help me on this please ?

See https://github.com/localtunnel/server?tab=readme-ov-file#setup

So, pass --domain app.domain.com to the docker arguments .

To mimic how the reverse proxy calls try:

curl -H 'Host: app.domain.com' http://localhost:4000/api/status

The above must work first for the reverse proxy to work.

And two other things: that app hasn't been updated for 5 years it seems.... And don't run additional stuff on cloudron server itself. We don't support this.

For the actual error, is localtunnel listening on the ipv6 interface where the health check tries to call?
