Well, in that case you can't do anything, I guess.
DDNS isn't down right now so your home router seem to have issues. Without the possibility to check that … no way to get it work again.
Now its showing no outage but many of my devices are still unable to resolve the DDNS. Has it been fully fixed or what do i need to do to fix?
My devices show this error when doing DDNS Test "The DNS Record for this DDNS domain could not be found by the DNS server. Please check the internet connection of this device." Doing a manual nslookup also shows non existent domain
This was an issue with my inofficial monitoring because the DNS servers stopped responding to TCP. Now I implemented UDP check for DNS which works better.
I don't know if there was an real issue (or maybe there is an ongoing one)
