Error: connection refused: localtunnel.me:<port> (check your firewall settings)

[alekseykulikov]

I'm not sure, if this issue is related to zuul or localtunnel, but I get it constantly on local machine and in travis. It does not throw immediately, usually after 1-5 minutes of running.

An example: https://travis-ci.org/treojs/idb-request/builds/92580535
I tried to restart this tests and it throws error randomly sometimes on 5th browser, sometimes on 11th.
Zuul could handle this error, and try to restart localtunnel.

Got this recently also

I've been seeing this as well, including when running on Travis (so it's not my local network).

Example here: https://travis-ci.org/jhiesey/stream-http/builds/118192592

[jhiesey]

After only seeing failures two days ago I gave my tests another try today and they all passed, so I'd guess it's just localtunnel.me being flaky.

[calvinmetcalf]

we've been seeing this pretty consistently on readable streams for iPhone and iPad https://travis-ci.org/nodejs/readable-stream/jobs/122543302

[lpinca]

I get this error constantly now, see https://travis-ci.org/primus/eventemitter3/jobs/131226437.

FWIW I've switched to zuul-ngrok and the issue seems to be gone.

[mappum]

I'm getting this occasionally. Might have to switch to zuul-ngrok.

[calvinmetcalf]

zuul-ngrok does the trick for readable stream, thanks!

Confirming zuul-ngrok is now working well even with parallel builds. @defunctzombie thoughts on making it the default since we do not actively maintain localtunnel?

it would help you get less issues on the long run :)

[lpinca]

The ngrok solution no longer works for me with default settings. I use the free plan and ngrok now limits the amount of open tunnels as expected:

You may not run more than 2 tunnels over a single ngrok session without an account

There is also an issue that prevents tunnels from being closed. To work around that the bind_tls option must not be set to both (default value).
Right now I'm using this configuration:

concurrency: 2
tunnel:
  type: ngrok
  bind_tls: true

[vvo]

Ahah @lpinca I am actually facing the exact same issue and you just solved it for me... Thanks a lot :)

[lpinca]

@vvo localtunnel works fine today :)

[SpainTrain]

A year later this seems to have returned https://travis-ci.org/SpainTrain/querystring-es3/builds/219168228

However, ngrok and sauce_connect tunnels both encounter failures as well (in the case of those tunnels, indefinite waiting/restarting).

sauce connect issue: https://travis-ci.org/SpainTrain/querystring-es3/builds/219370020

The only way I was able to get this working on travis was setting concurrency to 1 and ensuring only one build is running at a time (this is with the default tunnel).
