Hi, here's what I did:

setup *.localtunnel.function.fr CNAME function.fr.
ping localtunnel.function.fr works
ping dsadsa.localtunnel.function.fr works
using lt --host http://localtunnel.function.fr --port 8080 fails

It fails because maybe_bounce() does not find any client and so return true; and respond 502 to client.

I wonder how this could work, I know it does, but can you help on this? Everything is up and running if you want to test.

Also, I am setting this up because I get "Not running" errors most of the time while testing with zuul/saucelabs.

How does ping dsadsa.localtunnel.function.fr works work if no tunnel has yet been established?

Because there's a wildcard DNS set on *.function.fr.

Maybe we can chat on gitte quickly to solve this.

Reading the code: https://github.com/defunctzombie/localtunnel-server/blob/master/server.js#L28

When doing a requets, it goes to maybe_bounce(), I have a hostname, I have a subdomain (localtunnel.function.fr is a subdomain), returns false.

AH! I know, is localtunnel compatible with being served on a subdomain? This is the case: I am trying to use --lt localtunnel.function.fr, it may break?

I think as long as the server code around identifying the "client id" (subdomain) is correct it should work. That code (using the module to do that) might be wrong or returning too much of the subdomain.

https://gitter.im/defunctzombie/localtunnel-server But you have to create it.

I suspect it is returning everything before function.fr instead of just the stuff before the first dot.

So the strategy is:

if no hostname return false (go to localtunnel app)
if no subdomain (clientID) then return false, but in my case, it's returning "localtunnel"

I will try to host localtunnel on a top level TLD, it should work then

Yea. I think the code could be made to handle this better. It may be that auto-detecting the "base domain" part is not a great way to do it and we can just accept an ENV var for the basename.

Yes, as a top level domain it should work.

So tried the toplevel, now it almost work:

> lt --host http://localtunnel.eu --port 8080
your url is: http://pgpnimhrzm.localtunnel.eu

events.js:72
        throw er; // Unhandled 'error' event
              ^
Error: connection refused: localtunnel.eu:46831 (check your firewall settings)
    at Socket.<anonymous> (/home/vvo/.nvm/v0.10.36/lib/node_modules/localtunnel/client.js:84:32)
    at Socket.emit (events.js:95:17)
    at net.js:441:14
    at process._tickCallback (node.js:442:13)

My server seems to not have any specific iptables rule set, strange

Make sure your local network is also not doing anything funky. Sometimes
outbound connections on high ports are blocked to protect against malware.

Sometimes it just works and I get a url but then going to the url, it says "no active client.."

specifying a subdomain will always work,untill I shutdown/restart the server and try to reuse the same domain, then it fails with connection refused, what is different from my server from yours localtunnel.me. that's magic

mhh might be a DNS problem, seems like *.localtunnel.eu does not resolves to the good IP..

Ok now it works but I still have the sort of caching issue that when restarting the localtunnel server, it will fail from the client side with "connection refused".

Maybe DNS configuration/caching involved or some unclosed connection somewhere
