Let's encrypt only valid for domain name with specific port

[Julilemo]

Hi,

For some reason my domain is only secured when I enter a specific port: https://nas.dmi-intern.be:5011 . When I try to visit the domain without the port number explicitly written, my website has the Synology NAS certificate and as follows is not secured.
What should I do to get the domain https://nas.dmi-intern.be secured as well (without adding port number)?

My domain is: https://nas.dmi-intern.be

My hosting provider, if applicable, is: Combell

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

I’m using a control panel to manage my site (no, or provide the name and version of the control panel):
Yes, Synology NAS DS916+ (version DSM 6.2.1-23824 Update 4)

Hi @Julilemo

@Julilemo

My domain is: https://nas.dmi-intern.be

looks like a NAS-intern configuration.

Check

https://www.synology.com/en-us/knowledgebase/DSM/help/DSM/AdminCenter/connection_certificate

To configure certificates:

You can change a certificate for a service to another certificate to suit your needs.

1. Click Configure to show all the services and the corresponding certificates.
2. Click the current certificate of the targeted service.
3. Select the proper certificate from the drop-down menu.
4. Click OK .

That's done with port 5011.

Do the same with port 443.
