After a recent deploy, I no longer was able to connect to my app. Not through a custom domain, and not through the *.fly.dev domain. Connections will just hang until they timeout.
I’m able to ssh onto the box and wget localhost successfully, but connecting from the internet has stopped working.
I’ve redeployed my latest change, still nothing. Rolled back to a working version, still nothing.
I’ve double checked my DNS and dig points to the correct IP address for the app.
I’m sort of at a loss as to how to continue. Is there an issue with fly? Or is there something I could debug on my end?
Similar problem here. My app is down after I scaled it. The scale seemed to work (dashboard shows it as successful), but https://MYAPP.fly.dev is not responding. Tried scaling it back, but again the dashboard says it worked but it’s not responding over the web.
Not sure what to do here. Our production app is completely down. I’ve tried restarting a few times and it still doesn’t work. My dashboard says everything is OK, and status.flyio.net shows no problems, but nothing.
We provisioned a new server in London and it appears to be misconfigured. I marked it as such and drained all instances from it. Your instance got rescheduled to another server and now your app is available again.
Briefly: if an app instance fell on that server, due to this particular kind of misconfiguration our proxy didn’t know how to route to it.
For a production app, it’s recommended to run with more than 1 instance, ideally in a different, close-by, region. Even though we work hard to make sure none of our servers go down, it happens sometimes.
@jerome Nope. Still not able to connect, even after a restart. My app is in Frankfurt though.
Not sure if this helps or not, but I found this output interesting from fly curl:
$ fly curl <my app's healthcheck endpoint>
