At v1.14.0, after your router reboot, can ihost.local access successfully? If no, may you provide us your system log & tailscale log?
Yes, locally i can access after reboot.
Usually i reboot iHost with local access in order to make remote access work again.
may you provide us syslog & tailscale logs via forum Message or Feedback in ihost.
Typical of customer service: it canāt be done. Donāt give up and demand that they do a tidy up, because if thatās true - theyāve got horrible mess in the configuration. What is the link? Fibre optic, ethernet or DSL?
I struggled with mine provider for a fortnight. In the end they took away their wonderbox and replaced it with a simple fibre modem so that I could connect my router and use mesh and VoIP as I wanted and not as the provider fancied. I didnāt sign the acceptance so they gave up without being able to complete the installation. Earlier they insisted that a simple modem could not be used for technical reasons, which was obvious nonsense.
I downloaded the full log. Which ones do you need?
Now i am thinking to fight with them, thank you for your support! 
aibridge-api, but more importance is tailscaleās log.
Thank you, i sent you api and docker folders from the log is a message!
Done.
Do you have administrator mode access to the router? If not, look on the internet for how to do this. There should be an option that resets the connection, e.g. once every 24 hours at night. That way you avoid having to fiddle with the power supply.
Thank you for the tip, i will check it!
From your logs. Not only tailscale, internal modules also fail with ETIMEDOUT. If you have any other router for trying again? We cannot rule out that it is caused by the router. We hope you can help us compare and verify it.
Unfortunately i can check it within a few days.
Maybe this helps:
If I unplug / replug the lan wire from iHost, the problem occurs too.
That means, no need to reboot the rooter, only disconnect / reconnect LAN wire to recreate the issue.
Well, it suggests problems with DHCP and/or assigning the IP address within your LAN. Did you change anything in your routerās settings? Maybe you assigned static IP addresses for other devices, on their sides (interfaces)? You mentioned a NAS device in one of your previous posts. Is there, by any chance, a DHCP services activated on your NAS? Check it out, because it surely fucks up everything if it is activated. You canāt have two DHCP servers at the same time on the same LAN.
No i did not change the router settings.
On my NAS, Openmediavault runs, that i did not reconfigured but only updated in the past weeks.
But you gave me a hint, so i will disconnect my NAS and reboot the router to find out whether the problem raises with iHost.
Still it is strange for me, this issue raised after iHost update. Until that evereything was fine.
In my firm belief, your problem has nothing to do with the iHost software update. Perhaps it has only now become apparent. In extremely high probability, it is related to LAN configuration errors. You mentioned that your router becomes unstable and you have to unplug it. What do you mean by āunstableā? What is happening?
The internet service starts lagging.
Not permanent slowdowns, but goes offline for some secs, kinda dropouts, while wifi streaming works (at least Windows does not show offline wifi).
I realise it during online streams mainly (meetings, radio etc.), normal websurfing does not show the problem.
It is annoying, because an online meeting is painful.
If i switch off/on everyday it works fine.
Seems to be some DNS problem. I assume that your router uses default DNS settings, this is providerās DNS server. If your skills are appropriate, check it out and see the overall parameters of your link. Use SPEEDTEST to see the lags and pings. Run the test on a computer using cable, and not a WiFi. Read this article on interpreting speed test results.
As far as AV streaming is concerned, itās not that simple as you see it. Slowdowns and dropouts usually have nothing to do with the link quality since their dependencies are quite complex. BTW, using WIFi instead of ethernet has nothing to do with streaming. However, radio links usually tend to be less reliable than cable, especially in locations with high radio activity (noise). Therefore, it may significantly affect AV streaming, especially in 2.4GHz band. Surfing and other such activities are not prone that much to link fluctuations.
Thank you, i do my best and come back!
