Letsencrypt is trying to validate my domain using an outdated IP address

alexluna · January 18, 2020, 5:21pm

I have moved my application hosted in AWS from a traditional VM host to a new VM with a Docker containerized architecture. Because of that the IP address associated to the domain names listed below were changed from the previous VM to the new VM.

In my old traditional host I’ve used certbot to generate a letsencrypt certificate for the domains which are not working now when they were associated to the previous IP address.

My new Docker architecture uses a Traefik proxy container to handle access to the other exposed containers behind it. It also manages letsencrypt certificates on the fly.

In order to setup and test the new architecture before redirecting my production domain names to the new IP address, I have defined an additional domain name to the new VM, which access the same docker container as the migrated domain names and that was working before and keeps working now after migration.

After migration, Traefik is able to generate letsencrypt certificates for the domain names that were already associated to the new IP address but isn’t able to do the same for the ones that had the IP address changed, apparently because letsencrypt is trying to validate the domain names using the previous IP address. In this later case, Traefik generates self signed certificates which are naturally identified by web browsers as a potential threat.

In order to stop letsencrypt from using the old IP address to validate the domain names must I need to revoke the old certificates generated using certbot?

My domains are:

Not working, IP address has changed:

checkupinteligente.com.br

www.checkupinteligente.com.br

Working, IP address hasn’t changed:

prod.checkupinteligente.com
prod.checkupinteligente.com.br

I ran this command:

Traefik handles letsencrypt certificates.

It produced this output:

This is Traefik’s log message regarding the issue:

“Invalid response from https://checkupinteligente.com/ [52.67.50.125]:”

Where 52.67.50.125 is the old IP address for the not working domain names.

My web server is (include version):

Server version: Apache/2.4.38 (Debian)
Server built: 2019-08-18T13:34:20

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

I’m using the following Docker images:

traefik:latest, running Alpine Linux v3.10
php:7.3-apache, running Debian GNU/Linux 10 (buster) (used for the web server associated to the working and not working domains above)

My hosting provider, if applicable, is:

AWS with a VM instance provisioned using docker-machine.

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

Yes, but through Docker.

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):

Traefik handles letsencrypt certificates.

Hi @alexluna

checking these both domain names

via https://check-your-website.server-daten.de/?q=checkupinteligente.com and https://check-your-website.server-daten.de/?q=prod.checkupinteligente.com there is the same ip address:

Host	T	IP-Address	is auth.	∑ Queries	∑ Timeout
checkupinteligente.com	A	18.228.24.153 São Paulo/Brazil (BR) - Amazon Technologies Inc. Hostname: ec2-18-228-24-153.sa-east-1.compute.amazonaws.com	yes	2	0
	AAAA		yes
www.checkupinteligente.com	C	checkupinteligente.com	yes	1	0
	A	18.228.24.153 São Paulo/Brazil (BR) - Amazon Technologies Inc. Hostname: ec2-18-228-24-153.sa-east-1.compute.amazonaws.com	yes

Host	T	IP-Address	is auth.	∑ Queries	∑ Timeout
prod.checkupinteligente.com	A	18.228.24.153 São Paulo/Brazil (BR) - Amazon Technologies Inc. Hostname: ec2-18-228-24-153.sa-east-1.compute.amazonaws.com	yes	1	0
	AAAA		yes
www.prod.checkupinteligente.com		Name Error	yes	1	0

What's your old, what's your new ip address?

Looks like you didn't change your dns entry, so the result is expected.

PS: Your http setup looks wrong. / answers with a redirect, but /.well-known/acme-challenge/random-filename has a timeout.

Looks like there is an additional instance (proxy?), perhaps that's the reason of a wrong redirect.

PPS:

Ah

My new Docker architecture uses a Traefik proxy container to handle access to the other exposed containers behind it. It also manages letsencrypt certificates on the fly.

Looks like that Traefik proxy doesn't work as expected. But I have no idea how that must be configured.

alexluna · January 18, 2020, 5:39pm

Thanks for the reply.

The old IP address is 52.67.50.125.

It was associated to the not working domains, including checkupinteligente.com.

It was never associated to prod.* domains, which have been always associated to the new IP address 18.228.24.153.

I have updated the original post to include this information.

JuergenAuer · January 18, 2020, 5:43pm

There is a certificate:

checkupinteligente.com, checkupinteligente.com.br, 
medicinadescomplicada.com, medicinadescomplicada.com.br, 
www.checkupinteligente.com, www.checkupinteligente.com.br, 
www.medicinadescomplicada.com, www.medicinadescomplicada.com.br

Looks like your old instance is active. And looks that your proxy sends the traffic to that wrong / not longer valid ip address.

alexluna · January 18, 2020, 5:49pm

Yes, this is the old certificate used in the old VM setup and generated there using certbot.

Yes, the old VM is still running as a precaution if I need to roll back for any reason, but at this moment there’s no domain name associated to it anymore.

My proxy doesn’t know about IP addresses, I only knows about domain names.

Must I revoke the old certbot generated certificate associated to the old IP address?

JuergenAuer · January 18, 2020, 5:56pm

Please read some basics about revocation.

mnordhoff · January 18, 2020, 6:06pm

The Let’s Encrypt validation servers use whatever IP addresses are in your DNS records (with minimal caching).

Can you provide more of your Traefik logs?

The error message with your old IP address is from yesterday. It may have been correct at the time?

I guess that's what it logs when https://check-your-website.server-daten.de/ scans your site and tries to access a /.well-known/acme-challenge/ URL that doesn't exist.

I don't know what that's about...

That looks like a real URL, but who knows what was accessing it or why...

As an additional information, the www.* domain names are CNAME records in DNS, pointing to the main domains, not A records.

alexluna · January 18, 2020, 6:29pm

Yes, that was the time I have changed the DNS entries to point to the new IP address.
