JLR SDD V165 having issues with Gateway module coding

Hi all,

I am trying to recode a Gateway module on an L405 Range Rover. 

I am getting the following error;

'A failure occured - Error code A0B = P2CAN response code 78 timeout error'

I have attached screenshots too.

It seems as though it is not downloading the files or being kicked out by the server? 

Has anyone has come across this and how to resolve?

Thanks
Nick
