JLR SDD V165 No Network Icon Failed to Download Calibration Files?

Recently some people have had problems with JLR SDD V164 and V165.

 

Problem 1:

After the update to SDD v165 there is no longer connection to the server. Look at the attached .jpg. Green on 164, but red on 165.

when going from V164 to V165. The icon is always red even if the internet connection tells me it is correct!

Problem 2: 

JLR SDD v165 installs fine and log’s in but cannot get online to download any asbuilt or calibration files using the current patches available.
This is what shows when trying to activate the network and what shows under network status.

Our customers have spent some time doing multiple troubleshooting, the issue appears to be isolated to Windows 7 ,  we suspect JLR have hardened their webservers to not support the legacy encryption algorythms supported in windows 7.

clean win 7. install sdd 165 – no connectivity
clean win 10. install sdd 165, patch with v164 patch – downloads working.

 

User report:

I can confirm, 165 with the 2 patches from 164…..Red Wi-Fi Icon but Downloads working 100%. Download is working but not for all module.
 
As per Topix , JLR as of 01-Sep-2024 changed the server security so no versions of SDD prior to 165.00 will download calibration files. They said Icon is not criteria for connectivity with server. You can check connectivity from setting.
They closed online access to all offline versions of SDD, they cut off all offline access. better have the calibration files somewhere.
They also do a trick with kvms. So after a flash they delete the file from vbf so you need to download it online each time. Better make the vbf files existing readonly.
