Here is good, but do read through https://community.home-assistant.io/t/remote-access-for-home-assistant/206072 and be aware that DuckDNS is having issues, again

I am operating a ISP connection with DS-Lite-Tunnel (German NetCologne). As far as I understand this means this is IPv6 only.
I want to set up Duck DNS with Let’s encrypt, but I do not succeed.

I operate a Fritzbox router, which is connected to a fiber modem.
I tried to enable port forwarding, but apparently fail quite hard as many things are strange:

The DynDNS client configured in my Fritzbox router sends a different IP address to Duck DNS (2001:[…]:e5ab), as other websites to display IP adresses (as my ISP Net Cologne https://www.netcologne.de/geschaeftskunden/service/meine-ip/) 2001:[…]:ac1e . How is that possible?

Fritzbox router displays for HASS setup (hosted at RPI4) has 3 IPv6 Addresses: fe80:[…]:9189, 2001:[…]:4615 and 2001:[…]:bce2. Which one should I use to forward to? My Fritzboxrouter initially takes the 2001:[…]:bce2
If in DuckDNS I manually configure any IPv6 address displayed by router for HASS setup, I can acess HASS locally out of my wifi, but not from eyternal (using a hotspot).

Any assistance is appreciated. I do not know where exaclty to start fixing the problem.
Kindest regards

First things first: Thanks for the link, I checked it, but it unfortunately does not help me

DuckDNS is having issues, again, that may be the cause of your problems

#

If you're using IPv6 you'd normally want to configure your DuckDNS hostname with the public IP your HA host has, not the router's public IP

lethal moss Oct 3, 2022, 8:23 PM

#

so basically the "internal" IPv6 addess? I know internal adresses do not exist anymore, but the one which is desiplayed in my router (2001:[…]:bce2)?

pale hatch Oct 3, 2022, 8:26 PM

#

Well, the internal address is the fe80 one

lethal moss Oct 3, 2022, 8:29 PM

#

so the DuckDNS domian should be linked with this IP?

pale hatch Oct 3, 2022, 8:30 PM

#

No. The internal address isn't accessible outside of your network

#

That's why I keep saying public IP

lethal moss Oct 3, 2022, 8:36 PM

#

so bublic IP is https://[fe80::7f1a:7777:aab4:9189]:8123/

#

correct?

pale hatch Oct 3, 2022, 8:36 PM

#

No

lethal moss Oct 3, 2022, 8:36 PM

#

entireing thi in my wifi works, but not from my (wifi disabled) smartphone

#

so portforwarding does not appea rto work?!

pale hatch Oct 3, 2022, 8:37 PM

#

I've already said that was your internal address

lethal moss Oct 3, 2022, 8:37 PM

#

sorry

#

let me reread everything

#

so the public IP adress of HASS may be 2001:4dd6:9ae8::5d2a:d8f:5612:bce2

#

at least thas what my router says

pale hatch Oct 3, 2022, 8:41 PM

#

So, configure your router to allow access through to that IP on port 8123, and try a tool like https://www.port.tools/port-checker-ipv6/

lethal moss Oct 3, 2022, 8:43 PM

#

doesnt look promising

#

Failed: We can NOT see your service on 2001:4dd6:9ae8::5d2a:d8f:5612:bce2 on port (8123)

Reason: Resource temporarily unavailable

pale hatch Oct 3, 2022, 8:44 PM

#

And that's the one that HA itself tells you it has?

lethal moss Oct 3, 2022, 8:49 PM

#

Thats what my router tells me

#

I assume there is no approach where HA directly outputs its IP adress?

pale hatch Oct 3, 2022, 8:51 PM

#

It should show it in the console, and also in the networks tab of the settings

lethal moss Oct 3, 2022, 8:51 PM

#

let me check

#

Crazy... displays an entire new address... starting indeed with fe80

pale hatch Oct 3, 2022, 8:54 PM

#

Which is your local address, not your public address

#

If your router supports port forwarding to IPv6, try that shrug

lethal moss Oct 3, 2022, 8:57 PM

IP Information
IPv4
IP Address: 192.168.0.176/24
Gateway: 192.168.0.1
Method: auto
Name Servers: 192.168.0.1
IPv6
IP Address: 2001:4dd6:9ae8:0:8944:d85c:305e:4615/64, fe80::7f1a:7777:aab4:9189/64
Gateway: fe80::3a10:d5ff:fe21:e5a7
Method: auto
Name Servers: fd00::3a10:d5ff:fe21:e5a7

#

thats what HA displays

#

so here we assume 2001:4dd6:9ae8:0:8944:d85c:305e:4615 might be the right one, which fails in portcheck, right?

pale hatch Oct 3, 2022, 9:00 PM

#

Yes, assuming you've configured your router to allow that traffic through

lethal moss Oct 3, 2022, 9:02 PM

#

the IP address is displayed nowhere in my router, so Im reseting the device in my router

#

need to leave soon... jetz deleted the device in my router and rebooted

#

lets see which Ip reappears

#

looks like there is no IPv6 address yet, only v4

#

alright, I think I need to end here

#

...at least for today

#

thanks alot for your assistance!

#

much appreciated!

pale hatch DuckDNS is having issues, again, that may be the cause of your problems

Finally today seems that DuckDNS is ok, looking at https://www.intodns.com/duckdns.org all the servers are responding

pale hatch Oct 4, 2022, 6:20 AM

#

Hopefully they stay up

lethal moss Oct 4, 2022, 7:08 PM

#

Finally I managed it. Thanks for your assistance. Your explanation with internal /external IP helped a lot to understand.
