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.

Here is the clue.
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.
But SDD v165 closed online acces for the all known
patch. They changed everything, patch does not work on
v165.
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.
