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.

My domain is: www.hendersonvilleha.org

I ran this command: Using Certify The Web

It produced this output: 2020-02-20 09:25:40.331 -06:00 [INF] DNS problem: SERVFAIL looking up A for hendersonvilleha.org - the domain’s nameservers may be malfunctioning

My web server is (include version): IIS Version 8

The operating system my web server runs on is (include version): Windows 2012R2 (6.3 build 9600)

My hosting provider, if applicable, is:

I can login to a root shell on my machine (yes or no, or I don’t know):

I’m using a control panel to manage my site (no, or provide the name and version of the control panel):

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you’re using Certbot): Certify The Web Version 4.1.7

We have been getting certifications for this domain for some time without a problem. This month we are now getting failures for this domain and the www prefix.

Certify The Web suggested that I post the problem here.

Hi @dlloyd

there is a check of your domain, ~~10 hours old - https://check-your-website.server-daten.de/?q=hendersonvilleha.org

ns89.worldnic.com is your name server.

There are some problems with worldnic.


There is no real solution.
