Letsencrypt old ip adress after migrate server


#1

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:
overalwifi.nu

I ran this command:
Create certificiate in C panel

It produced this output:
The domain “www.overalwifi.nu” resolved to an IP address “37.46.136.198” that does not exist on this server.

My web server is (include version): cPanel

The operating system my web server runs on is (include version):
Centos 7

My hosting provider, if applicable, is:
Myself

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

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

After migrate my server this morning, Letsencrypt gives an error that www.overalwifi.nu resolved to my old ip adress. At every ISP overalwifi.nu is linking to the new ip address. How can i fix this?

Hi,

Please check the time when this error occurred in autossl…

This is actually coming from autossl (which you could found on cPanel if your host enabled for you). (The autossl run might be completed before your IP is propagate to the DNS resolver cPanel use)

What you might want to do is either go to the autossl (SSL/TLS status) interface of your cPanel account and click “Run Autossl” then wait until the run is finished. (If successfully, you would get a certificate. If not, it’ll still present an error message)

If you don’t have the "run autossl "button, you would need to wait till server’s cronjob run autossl check for each account or contact your host’s support for help.

P.S. Nice warning: Due to different autossl settings, when it’s executing & obtain certificate from an CA, your site might be temporarily unavailable until the new certificate is issued.

Thank you

This error is from autossl…

WARN “Let’s Encrypt™” DCV error (cpanel.overalwifi.nu): DNS problem: NXDOMAIN looking up A for cpanel.overalwifi.nu (urn:acme:error:dns).

There is no file in the acme-challenge directory. If i add a file i can reach it trough my webbrowser.

On the head domain overalwifi.nu is the certificate now valid with letsencrypt. Mail/www isn’t working because the NXDOMAIN error.

One of the domain’s nameservers says cpanel.overalwifi.nu doesn’t exist.

http://dnsviz.net/d/cpanel.overalwifi.nu/WxfTXA/dnssec/

For the mail and www subdomains, some of the nameservers return different IP addresses, or don’t work, but none of them appear to return NXDOMAIN.

http://dnsviz.net/d/overalwifi.nu/WxfUKw/dnssec/
http://dnsviz.net/d/mail.overalwifi.nu/WxfULQ/dnssec/
http://dnsviz.net/d/www.overalwifi.nu/WxfULw/dnssec/

You may need to sort out the DNS issues before the validation will work. Or at least work reliably.
