Until yesterday my HA worked fine. Today i could not reach the HA App away from home. I use Tailscale to connect.
When i came home no connection was possible on my desktop, laptop or GSM using the homeassistant.local:8123 or by IP address.
I connected a screen directly to my Raspberry Pie and restarted HA. On screen i can see that HA starts up normally. showing the IP4 IP
Automation seems to keep on running but i just can’t get into the app.
When i open my tailscale connection i can see that the HA IP has no green light so it can’t be reached.
On the RP the internet leds are blinking.
Is there more information that i can provide to seek for a solution. Help Appreciated because i don’t see the answer to this problem.
What do you mean? What do i have to look for? For me this is not as simple as the most
Any advise to point me in the right direction could help.
What i also noticed is that my TADO connection is also lost.
On my router i can’t find the IP adresses of TADO Bridge or my RP4.
I have no clue why this happened because everything worked fine and something changed during the day or night yesterday that caused the loss of these 2 devices.
Update, got things working again but don’t know why exactly.
I contacted my Network distributor and it seemed the day things went wrong there was a big internet connection loss in our street. They think that in the period of restarting the internet connection something did go wrong while creating the IP addresses. My HA run’s on a static IP ending on 100. They advise me to chose a smaller number becouse this one is to close to the random chosen ones.
Don’t know if this is the answer but didn’t find any other reasons
In other words, being a little bit more technical, you didn’t configure your router for Static IP, and the IP address used was allocated dynamically using DHCP (it often just picks the next one available).
This explains the ‘random’ aspect of your IP addressing dilemma, when your external network interruption was eventually rectified, and your router restarted.
This would have made the penny drop as you would have noticed any IP address issues your network distributor help desk hinted at.
Go back, check how you are configuring the choice of allocating IP address, check the router DHCP settings, and adjust accordingly, otherwise you may find the problem may happen again.
I strongly recommend pre-allocating Static (fixed) IP addresses for everything. That way you are in control and not subject to the DHCP whims of your router, you know what to expect, and where to look if a device cannot connect. Your networked devices, looking for each other to communicate will also be able to consistently find them easier and faster. If anything goes down, it will come back in a known state on their allocated IP address, because you told it to.
