CRM2015 SSIS Cozyroc Connection Mgr - Token node not found.

[Siopold]

I created a simple SSIS package which was running correctly nightly via an SQL Server job.

I used a login and password in the SSIS Dynamics CRM Connection Manager. the password was changed at AD level and the job stopped running. 

I  went into the SSIS package in Visual Studio and updated my password to my NEW passowrd in the Cozyroc Dynamics CRM Connection Manager

Tested connection - all was fine

When I attempt to run the job in debug in SSIS 

I now get; 

An error occurred with the following error message 'Token node not found'

and a further message 

id3242: The security token could not be authenticated. 

Obviously it is failing an authentication somewhere, but where?

I am running an IFD on premises CRM2015

Do I need to reset something?

Any help would be appreciated. I am likely to be missing something simple here.

Regards
