My domain is: [carpentier.trumanetcooper.com](http://carpentier.trumanetcooper.com)

My server is a synology NAS. The certificate is supposed to be valid until 2020. That’s what i see in my certificate tab in the nas setting. yet , firefox says it has expired

I have a similar problem on another domain linked to another server : [https://ombi.letty.in/](https://ombi.letty.in/)  
This goes to a ngix server on ubuntu.

When i do the command : certbot certificates

i get:  
Domains: ombi.letty.in  
Expiry Date: 2019-12-14 19:09:17+00:00 (VALID: 62 days)  
Certificate Path: /etc/letsencrypt/live/ombi.letty.in/fullchain.pem  
Private Key Path: /etc/letsencrypt/live/ombi.letty.in/privkey.pem

So its supposed to be valid, yet firefox says it has expired. Feels like its the same problem than on my nas.

what am i doing wrong?  
thank you!

there is a check of your domain, 30 minutes old - [https://check-your-website.server-daten.de/?q=carpentier.trumanetcooper.com#certificates](https://check-your-website.server-daten.de/?q=carpentier.trumanetcooper.com#certificates)

There is a

```nohighlight
CN=deluge.letty.in
	17.07.2019
	15.10.2019
expires in 2 days	deluge.letty.in - 1 entry

```

used, so the certificate has the wrong domain name.

And you have created a new certificate:

| Issuer | not before | not after | Domain names | LE-Duplicate | next LE |
| --- | --- | --- | --- | --- | --- |
| Let's Encrypt Authority X3 | 2019-10-13 | 2020-01-11 | [carpentier.trumanetcooper.com](http://carpentier.trumanetcooper.com) - 1 entries | duplicate nr. 1 | |
| Let's Encrypt Authority X3 | 2019-09-16 | 2019-12-15 | [carpentier.trumanetcooper.com](http://carpentier.trumanetcooper.com) - 1 entries | | |

Ah - checked with my browser, now there is the expired certificate with the correct domain name visible.

Check your NAS, so the new certificate is used. Then restart your NAS. Same with your other domain.

hello,  
thanks for your answer, it all works now. I was also mistaking in the port forwarding of port 80 and 443 regarding my nas and other server.
