Domoticz Challenge failed for domain

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: domo-test.synology.me

I ran this command: sudo /etc/letsencrypt/letsencrypt-auto certonly --webroot --email wakior@hotmail.fr -d domo-test.synology.me -w /home/pi/domoticz/www/ --debug-challenges

It produced this output:

Challenge failed for domain domo-test.synology.me

IMPORTANT NOTES:

My web server is (include version): Domoticz v 4.10717

Thank you for your help

Hi @wakior

your configuration is completely curious - see https://check-your-website.server-daten.de/?q=domo-test.synology.me

You have ipv4 and ipv6:

Host T IP-Address is auth. ∑ Queries ∑ Timeout
domo-test.synology.me A 82.65.4.175 Clichy-sous-Bois/Île-de-France/France (FR) - Proxad / Free SAS Hostname: 82-65-4-175.subs.proxad.net yes 1 0
AAAA 2a01:e0a:2b5:d940:211:32ff:fe94:1093 Nanterre/Île-de-France/France (FR) - Free SAS yes

And you have created a certificate - today:

Issuer not before not after Domain names LE-Duplicate next LE
Let’s Encrypt Authority X3 2020-02-07 2020-05-07 domo-test.synology.me - 1 entries duplicate nr. 1

And your ipv6 - works, the certificate is used:

Only your ipv4 doesn’t work.

So I don’t understand your error message - because you have created a new certificate today.

And check your ipv4 configuration, so your ipv4 uses your certificate.

It’s the NAS.
When I configured de DDNS, he ask me to configure a certificate. but I don’t have access to the certificate created by Synology with letsencrypt.
May be I had to refuse when the NAS asked me to configure certificate with letsencrypt.

For the IP, It’s my provider I don’t have hand on it. (IP4 an IP6)
