Is that maybe let's encrypt blocked?

Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

I ran this command:

It produced this output:

My web server is (include version): Apache Tomcat

Hi,

What’s your domain name?
And if I understand correctly, you already requested a certificate (and installed?) But now when you tried to open the website it said connection refused?

that is jskgo.duckdns.org , deavejsk.duckdns.org, jsktot.asuscomm.com
I used duckdns and dnsomatic without using asus ddns
yes I use filezilla, apache tomcat website
It is equipped with the basic function of issuing the certificate of the asus router. In the process, I also used certbot.

Hi,

All three websites showed not resolved for me, and they do have valid certificates now.
Did you manage to resolve the issue?

P.S. I’m sorry for the late reply, i missed the notification from this post.

Currently, it is registered to dnsomatic at the following address.
It is still marked as failed registration.
