there you go. The used DDNS is not valid and no IP address associated

No valid IP addresses found for nanooker.dns.navy

I have no idea what to do now

quite simple. You need to ensure to have correct IP address stored on your DDNS provider. Actually it looks like your privat one from your local network. For sure this is not working that way. I checked the domain and this is the result:


basically you would need to find out which device is using Probably there is a service running updating your DDNS wrongly.

Next to this you tried to often requesting a certificate. There you got blocked by letsencrypt

There were too many requests of a given type :: Error creating new order :: too many failed authorizations recently: see https://letsencrypt.org/docs/rate-limits/

Not sure how long the blocking will be but usually it’s gone after a day

the 192.168.2 is the raspberrypi with dietpi.
installed is samba and baikal
nothing more

well you need to find out what and why your DDNS is updated incorrectly. Otherwise you never will be successful

It runs over another raspberrypi pihole which resolves the dns requests in the lan. but i turned it off for a while, still it does not work.
it does not work. And letsencrypt is also not blogged.
I thought maybe the error is on this raspberry.
Baikal I still have set up on my webspace, there it runs secured with https with letsencrypt. I would prefer it with the raspberry but if it does not work you can not do anything. Thanks again for your patience and help.
Since I gave away a lot of data in the forum, is it possible to delete some of it?

probably you could try a different DDNS provider. Or you check with your ISP.

I have taken yesterday times another ddns provider this has also brought nothing. I will ask my ISP provider tomorrow. I still have a synology. And I have also tried this with no-ip. Despite intervention of the support on my device no connection was established. I have then given up. Sometimes there are things in life that are not granted to you :smiley: :wink: :thinking:
Thanks a lot Joulinar

You are welcome. Hopefully your ISP can help on this.
