Can't renew the cert

[hf81970]

My domain is: www.d5techs.com

I ran this command: certbot renew

It produced this output:
Failed authorization procedure. www.d5techs.com (http-01): urn:ietf:params:acme:error:unauthorized :: The client lacks sufficient authorization :: Invalid response from http://www.d5techs.com/.well-known/acme-challenge/9Cj5J1k7DoGH2luMN5DBIQ9Q0iicLIy6ViK4ObtMUKQ [54.156.208.31]: 404

My web server is (include version):nginx/1.12.2

The operating system my web server runs on is (include version): Ubuntu 16.04.3 LTS

My hosting provider, if applicable, is: Aliyun

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):no

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you’re using Certbot):certbot 0.31.0

Apparently it is one of your website’s IPs:

www.d5techs.com.                      600  CNAME  www.d5techs.com.s.strikinglydns.com.
www.d5techs.com.s.strikinglydns.com.  60   A      34.238.46.163
www.d5techs.com.s.strikinglydns.com.  60   A      54.156.208.31

Strikingly seems to be a “free website builder”.

Oh I see. Thank you.

When the source ip is from China, the A record is the ip of a ubuntu server on which we use letsencrypt.
When the source ip is not from China, the CName record is a strikingly domain. The dns record you list above is for this one.

Then how can I renew the cert on ubuntu server?
