Microsoft Dynamics AX Update Installer reports "No Internet Connection Found..."

I downloaded the update installer from LCS, started it, accepted the license terms, selected "Download and install updates", clicked Next and it reports "No internet connection found. Please verify that your internet connection is available."

Since I had just downloaded it, and am now posting this message from the same machine, my internet connection is clearly working perfectly. So presumably, what it really means is "the installer can't connect to the specific host and port it needs to access."

How do I find out what it's trying to do short of running a network sniffer? Which host/port is it trying to reach?

Or can I just download the cumulative updates from somewhere else?

Isn't anything interesting in event logs?

Derek,

You can download the required update from a system which has unlimited access to internet. After download is completed you can choose to save the package or just install.

You may save the package to a location and later move it to any system to install it without needing to access internet

This doesn't actually answer the question as I need to know exactly which ports are being used, and presumably blocked, in order to request they be opened. A request to have a server given uncontrolled access would not be permitted by our current security policy.

Hi Derek,

As I remember while updating Ax 2012 I first downloaded the package on the development machine then the same downloaded file was used on TEST environment without any need for an internet connection. And after this I slip streamed my ax installer itself.

I did not come across any specific ports while doing the update myself.

At this point of time I think you will have to look into event logger as Martin said.

Looking more into this, I just realized that the update package is trying to browse to

update.lcs.dynamics.com/.../Index when you hit Next on the Download package screen. If you have not yet resolved your issue and you can still reproduce it, you try to manually browse to that link (or the shorter version update.lcs.dynamics.com) and see if it opens fine on that machine (do not forget to do this from an Internet Explorer).

The links given seem to just bounce back to the default LCS page I get when I log in.

However, having played around a bit today, I realised that the problem seems to be the choice of browser! My default was set to Chrome, but, since this is Windows 10, the installer seems to try to open a link in Edge! Changing my default browser to IE11 actually gets the download to start on my development machine. Hopefully, I can then save it for use on the server later.

It still seems to be a very roundabout way of getting an update when, presumably, Microsoft could have either just posted a link or used a request mechanism to distribute links in the same way Cumulative Updates for SQL are sent out. I am not impressed.

I was already trying this on a development machine having previous tried, and failed, on the server. I still don't understand why Microsoft don't just provide a link to download, perhaps time-limited and emailed only to a registered email address.

@StarNamer: But you don't change classes of SQL Server (potentially conflicting with changes done by Microsoft), do you? It can happen with AX application updates if you modify standard AX code, therefore you're comparing very different things.

By the way, thank you for letting us know about the browser issue.

Microsoft released a fix for the update installer to support TLS 1.2,

Login to LCS - download the latest version via the Updates tile (under the More Tools section of your AX 2012 R3 LCS project).

For some time now I do not check this update tile button but search it in issue search. issue search does not reflect reference to "update installer"
