SSL Mismatch for DDNS


My DDNS is supported through The IP address that I have for is I have my SSL cert for that DNS through Lets Encrypt. The issue that I have is that when I look at SSL checker, I get the following message “ resolves to”. Looking further into this situation I have found that “The security certificate presented by this website was issued for a different website’s address.” Can this be fixed as soon as possible so that I can access my server through my DDNS with security.


Hi @ddeare

checking your nameserver entries this is wrong:

Host T IP-Address is auth. ∑ Queries ∑ Timeout A yes 1 0
AAAA yes A yes 1 0
AAAA yes

Your name servers:

You have to change your dns settings, so that the 73.* - ip address is the address of your domain.

The 95.* ip has a certificate
	18.02.2019, - 2 entries

Looks like a domain forwarding or something else. You must set the A record to 73.*


This is NOT in sync with their system.
Are you using their IP sync tool?:


My account updates manually through the web interface. Using that interface, I have updated the account several times. I have an open support request to resolve.



Where is this  A

combination defined? The nameserver is

There you have to change something.


If you look at the HTML on, it’s a forwarding service. It includes within an iframe.

So the IP address is correct, but the setup is wrong. It’s an HTTP forwarding service instead of just an A record.


This has got to be the worst DDNS service (option) ever created.

DynDNS Updater Url
Emphasis on URL.
It doesn’t set the FQDN to your IP (like most other DDNS services).
It sets the FQDN to a page that links to a URL (that wraps your IP URL in a frame).


Site URL produces a page like:
[abbreviated for clarity]

<!DOCTYPE html PUBLIC ...>
<html xmlns="" xml:lang="de" lang="de">

The site uses the term “DynDNS” which seems to conflict with Oracles use of that same term:
The Free Services include the DynDNS® dynamic DNS service and all other services that Oracle makes available to You free of charge on Oracle’s Websites.
