tailscale integration : asks for API key every other day, sometime even multiple times per day

[ledshark24]

The problem

The tailscale integration asks for a new API key every other day, sometime even multiple times per day.

The API access token given to the integration is supposed to be valid for 90 days. Yet I have a notification to renew it in HA every other day. Twice today.

How to reproduce :

1. set up tailscale integration
2. provide a 90 days token
3. wait a few days / hours
4. tailscale integration uses HA notification to ask for a new token. Provide a 90 days one, it will last a few days / hours.

Same issue here

[TomDijk]

Same here:

Authentication failed while fetching tailscale data: Authentication to the Tailscale API failed

[ledshark24]

Got another one about half an hour ago. Logs may not be helpfull :( same logs than @TomDijk

[Tomanic-glitch]

Same issue for me as well.

[danivovich]

I’m also experiencing this, fresh api tokens are being claimed invalid by the integration in about a day or so.

This issue is a duplicate of #150938, but there is slightly more information on this ticket.

Happy to provide more information but I’d need some guidance on what to gather from where and how.

Thank you!

[mcmtaged4]

also having this issue, normally dont really need to think much of tailscale. this week i swapped the keys twice, and is currently asking which would be a 3rd time.

[AlexKusnezov]

Same here, found out that either restaring HA, or via Spook disable, enable an integration action temporarily resolves that

[Feighery]

Same here.

2025-08-22 17:43:00.419 ERROR (MainThread) [homeassistant.components.tailscale] Authentication failed while fetching tailscale data: Authentication to the Tailscale API failed

I checked Tailscale logs on the console and there is no corresponding alert or log for that timeframe on tailscale.

[ledshark24]

I made the upgrade to 2025.8.3 this morning (around 10am local time) Tailscale was in the failed status when I did it and the restart cleared the failed status for a time. It was incident free for most of the day. Then...

2025-08-22 18:42:39.639 ERROR (MainThread) [homeassistant.components.tailscale] Authentication failed while fetching tailscale data: Authentication to the Tailscale API failed

[mikegull]

Restarting HA cleared the error. Wondering if it's an API timeout issue or similar. Will attempt restart of just integration next time.

[Feighery]

I can also confirm that rebooting HA cleared the error so I will monitor to see if it comes back.

[ledshark24]

Same here, a full reboot clears the issue for a time, yet a "simple" restart of HA did not.

[josephjaskolski]

Seems like the issue has been resolved. It coincided with upgrading to Core 8.3 yestereday. I left the integration down and did not update the API key. The integration came up on its own and has been stable for 24hrs after the upgrade.

Good to know, I'm still on 8.2 and won't be able to uodate til next week, but for me disable the enable integration action (Spook) did the trick (running for 48h without complaints)

[ledshark24]

Sorry to disappoint, @josephjaskolski but I've upgraded to 8.3 and still had the issue at least one.

Sorry @AlexKusnezov, stupid question but what does this mean? i cannot for the life of me find a way to disable the enable integration action anywhere in spook.

Sure, meant the actions that come with the spook integration:

Thank you! That seems to have worked for me, that or the upgrade to 8.3 I suppose.

Just freshly installed Tailscale integration yesterday, restarted HA after, HAOS up to date. Logged in this morning to a failed API message. Soft reboot (not restart) and the notification has disappeared.

[jkosatko]

Same issue here. Last key updates: 14.8.2025 24.8.2025 28.8.2025 29.8.2025 30.8.2025 Tailscale and HA works otherwise quite fine.

[rlowellfl]

Same issue here on 8.3. Reloading the integration clears the error for a time and then it reoccurs within 24-48 hours.

[Fayyaadh]

Same for me as well. It doesn't accept the API key at all.

[Bygood91]

Same for me.

[madtraxx18]

2025.8.3 with os 16.0 seems to be running fine, did a full restart after the update.

[jpettitt]

I'm pretty sure this is a race condition or poor network error recovery. Regenerated the token and saved it in a secure note in 1password. When HA fails I give it the same token from before and it works for a few days before failing again. In other words it's not actually an expired api token - even if HA thinks it is.

Tailscale add on 0.26.0 
Installation method: Home Assistant OS
Core 2025.9.0
Supervisor 2025.08.3
Operating System 16.1

[nsleigh]

I find just restarting the integration resolves it. So as @jpettitt said it seems like a race condition.

[ledshark24]

Everybody is commenting, but which one of you has tried a full system reboot? So not just home assistant a full reboot

I did and got this error right away, for me it's, like mentioned before, using disable/enable an integration action via spook the current workaround. Nor reboot needed and this keeps it quiet for a couple of days
