Is Duck DNS having problems?

1

Hello all,

Since about 24 hours ago I (and Google Assistant) cannot access my Home Assistant installation via the Duck DNS domain.
I’ve done the following to troubleshoot the issue:

  • restarted router, modem and Raspberry Pi
  • rechecked the port forwarding
  • rechecked the DMZ settings on the modem
  • tried to access HA via the local name - works
  • tried to access HA via the external IP - works
  • deleted and recreated the Duck DNS domain
  • added a secondary domain on Duck DNS - works :open_mouth:

Now I am scratching my head trying to figure out what the heck is happening. But I am 99% sure that there is something working with the DNS service. I haven’t changed anything on HA in the last days and Duck DNS was untouched since about 3 months ago.
Is anybody else having a similar problem?

Thanks!

On the duckDNS web admin page, does it report the correct public IP for your router?

3

Sorry for forgetting to mention…
Yes, the reported IP is correct and it seems to be propagated to all majod DNS backbones.

No problems here.

Are your security certificates valid?

Is your system clock time correct?

It looks like I have a problem with the certificate renewal…

I can’t figure out what the problem is…

In the end I reinstalled the add-on and it works now.
I’ll have to set up a reminder 3 months from now, not to be taken by surprise.
Thanks!

Exactly the same problem every 3 months :frowning:

Renewal never works and sadly this time, reinstalling the add-on hasn’t helped

Same at me, three days and counting, I donate every month to duckdns, but no support !
Now started to switch back to NOIP

Bump on this
Anyone else having problems with DuckDNS today?
Mine works intermittently.
External IP and internal from LAN (or VPN) works fine.
I had the same experience on Tuesday this week.

If you donate every month, why not buying your own domain ??

f.e. ha.blagojg.eu will cost you €7.99/yr at TransIP and works fine with Let’sEncrypt

got an entry in the log now for the first time - unfortunately it doesn’t say me much more than it’s DuckDNS related…:
