Unable to connect after some idle server time..

[nebulon]

@robi does restarting the server always reproduce the issue? This might make things easier to debug. It may be that TeamSpeak cannot deal with DB reconnection properly and during a server startup, the database is not yet accepting connections, while TeamSpeak already expects this?

[robi]

@nebulon yes, that is reproducible. And your theory is plausible.

Since it's a tiny fast app, it may start up too quickly.

[girish]

I tried to reproduce this with several reboots but couldn't . Even tries reloading mysql server when teamspeak was running and it seems to reconnect automatically. So, the issue seems to be something else. I did cleanup many bugs in the package though and made a new release.

[robi]

@girish ok will try new package.

Still have the same issue, here's the log:

Can we add a better app monitor check, so it does this restart for us?

As right now it thinks it's running when it actually isn't.

[nebulon]

Thanks for the logs. This is interesting, since the first failing log indicate that the TeamSpeak process is being restarted at least twice.
So I think there are two fixes required:

1. Ensure the teamspeak process is always restarted probably with some delay to not overload the system.
2. Fixup the healthcheck to actually check for teamspeak and not the nginx process, serving up the index.html page

[nebulon]

@robi I've updated the package now to check the actual teamspeak daemon is running for the healthcheck, as well as restarting for longer. This should hopefully solve your case as well.

[robi]

@nebulon Thank you so much! This is awesome work & timing.

We'll test it at the next maintenance window

Lots of love

[robi]

@nebulon The fixes seem to work, but we found another instance where it doesn't.

As we clone an existing TS server, the new one autostarts and cannot be connected to until it is manually restarted.

Should be reproducible.

[nebulon]

@robi I can't reproduce this. A cloned app works just fine here, of course ports have to be adjusted. Also note that if you have multiple TS instances, client will always by default connect to the app with the default ports configured, regardless of domain.

[nebulon]

I believe I've fixed those things now with the latest just released package version.

[robi]

Looks good so far, thanks @nebulon
