Applying CU 13 updates yields No Internet Connections Available
Recently while trying to apply an update one of our AX 2012 R3 environment, I ran across a “No internet available” when running the AxUpdate installer. The internet connection was most certainly available on this server. I verified this by running a browser and pinging outside sources along with doing an nsLookuop and also reviewing the firewall rules.
The next stop was to look in LCS, which shows a case submitted but no resolution available, however the remarks were “Updated installer to use TLS 1.2 for HTTP requests.”
After seeing that I had an idea what was happening now, the installer is using .NET 3.5 but that does not support TLS 1.2, the fix is to apply a registry change. I had this same issue with another application.
Editing with the registry needs to be done with caution, if you make a wrong entry the computer will become unusable. Proceed with caution and take an image of the computer so you can revert if necessary.
Navigate to the following keys and add the DWORD value of 1.
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\v2.0.50727]
“SystemDefaultTlsVersions”=dword:00000001
And
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\.NETFramework\v2.0.50727]
“SystemDefaultTlsVersions”=dword:00000001
The entries should look like this when you are done.
That is all that is needed, a reboot is not necessary for this to take effect.
Run the installer again and you will get the Log in to LCS screen.
