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.

Hi @Jayz

checking your domain that looks ok - https://check-your-website.server-daten.de/?q=jjongnas.duckdns.org

Port 80 is open and answers, checking a random file in /.well-known/acme-challenge there is the expected result http status 404 - Not Found and a Synology page.

So if your Synology configuration is ok, the certificate creation should work.

–> First step: Check, if there is an update of your DSM.

You have some older certificates:

Issuer not before not after Domain names LE-Duplicate next LE
Let’s Encrypt Authority X3 2019-09-22 2019-12-21 jjongnas.duckdns.org
1 entries
Let’s Encrypt Authority X3 2019-07-19 2019-10-17 jjongnas.duckdns.org
1 entries
Let’s Encrypt Authority X3 2019-05-15 2019-08-13 jjongnas.duckdns.org
1 entries

But why don’t you use the certificate created 2019-09-22?

You use a self signed certificate.

CN=synology.com, O=Synology Inc., L=Taipei, C=TW
	30.11.2019
	17.08.2039
expires in 7197 days

Where is this certificate created 2019-09-22?

Your port forwarding looks ok.

There

is the expected result. Port 80 extern -> port 80 intern.
