Posted on by BryLearnsBC 225
Anyone experience disconnections happening recently with their On-Prem NAV?
 
We cannot identify why this is happening to some users and not all.
Purchasing, Finance and Admin users are the most affected. No input yet from our warehouse team
 
 
As per the Event Viewer - Application
 
Error message is as follows.

    From the error message, it seems that the client cannot access the server. Is it a network or client problem? 
    Message: The session could not be retrieved from the server. The application will close. You can try reinstalling the user client first.
     
    Thanks.
