Problem with synology nas

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:nasrosny.eu

Hello,

I bought this domain name “nasrosny.eu” for my synology nas and impossible to put your ssl certificate
but i tried with a free domain name from noip.comnasaurel.ddns.net” and its work perfectly

Is there any issue withe .eu domain names?

Hi @aurel002

perfect? No, there are some errors.

There is one ip address ( https://check-your-website.server-daten.de/?q=nasaurel.ddns.net ):

Host T IP-Address is auth. ∑ Queries ∑ Timeout
nasaurel.ddns.net A 78.118.242.98 yes 1 0
AAAA yes
www.nasaurel.ddns.net Name Error yes 1 0

but your standard port 443 has the wrong certificate:

Domainname Http-Status redirect Sec. G
http://nasaurel.ddns.net/
78.118.242.98 302 http://nasaurel.ddns.net:5000/ 0.083 D

Only port 5001 is correct.

The standard port uses the certificate

CN=maisonrosny.ddns.net
	24.02.2019
	25.05.2019
expires in 15 days	maisonrosny.ddns.net - 1 entry

so it's the wrong name.

Your eu domain has two different ip addresses ( https://check-your-website.server-daten.de/?q=nasrosny.eu ):

Host T IP-Address is auth. ∑ Queries ∑ Timeout
nasrosny.eu A 185.26.105.244 yes 1 0
AAAA yes
www.nasrosny.eu A 78.118.242.98 yes 1 0
AAAA yes

Checking the urls you see the problem:

Domainname Http-Status redirect Sec. G
http://nasrosny.eu/
185.26.105.244 301 http://www.nasrosny.eu 0.047 D

Your NAS runs on the 78.* ip. But the 185.* ip has a wrong redirect, http://nasrosny.eu/.well-known/acme-challenge/check-your-website-dot-server-daten-dot-de is redirected to http://www.nasrosny.eu, it should be something like

http://www.nasrosny.eu/.well-known/acme-challenge/check-your-website-dot-server-daten-dot-de

No, you have a lot of configuration errors you should fix.

Oh wow . I dont know where Come from this IP 185xxx. How a domaine Can have 2 IPs? How tout remove thé wrong one?

Thanks

A domain may have a lot of ip addresses, ipv4 and ipv6.

Check your dns settings.
