"Tailscale is not online" problem

chudak

I don't know exactly where to look :(

On a high level, only what I see is TS service is green (which is confusing but that's in a different thread and unrelated) and TS connection status is down.

My use case is:

pfS runs TS
iPad runs TS
iPhone runs TS
Windows 11 VM runs TS

So when psF is down, others actually work fine.
I even noticed that routes get resolved.

TS connection status is down.

isn't the script working for that ?
script tries to ping and if it fails, it will restart the service.

That's an interesting part.
Yesterday I found TS down

I tried to start it manually, and switched Kea DHCP to ISC DHCP and back, removed /tmp/kea4-ctrl-socket.lock and could not make it start.

Then today in the morning - everything is up and running normally

??!!

I don't see how one thing could interfere with each other.

But, I'm still using ISC-DHCP for that customer.
Can't switch to KEA yet...

Do you know by chance how to catch related to TS stop/start errors/warnings in the logs?

You can search old system logs in /var/log directory if I'm not mistaken. Shouldn't be hard to find it, I mean, if problem started yesterday at 15:00hrs, so there you go.

TS in conjunction with pfS instability is really frustrating
I’m travelling now and TS is simply down with the error:

Error executing command (/usr/local/bin/tailscale status)

Health check:

- not logged in, last login error=invalid key: API key does not exist

unexpected state: NoState

So far nothing I’ve done, rebooting, deleting a lock file, nothing helped.

Thx G.. I still have OpenVPN as a backup option.
I’m surprised no one else is complaining about this…

@chudak did you create the key at the tailscale's console and then imported it to pfsense ?
also, set the key to do not expire.

I did set my key to not expire.
I have used the original key with pfS and did not regenerate it
And have seen it’s working normally after this error.
So suspecting it’s unrelated

I’m hesitant to mess up with keys now as it used to work literally two days ago.

Ok, if the problem happens again, try to create a key, import it, and then set it to "don't expire".
