It looks like 10943 is responding correctly from your new address.
As you may have noticed, the results of the call to https://octopus.ilogs.com:10943 has a “Not Secure” flag at the very top of the page.
This is likely because this address has been added to an exception list in your browser. You see the exact same page, from your new url, if you click on “Advanced”, scroll to the bottom of the page and click on “Proceed to servername”
This means 10943 is responding correctly.
Your tentacle will still require a 2-way handshake between the Octopus Server and the Tentacle in order for proper trust and communication, so although the connection to 10943 is not secure, your ongoing tentacle communication will be over tls.
You can read more about that, here: Octopus - Tentacle communication - Octopus Deploy
If you are having troubles getting your tentacle to communicate, we have a list of almost every possible scenario, over here: Troubleshooting Tentacles - Octopus Deploy
Otherwise, you can reach out again, if you are still not able to get everything working.
