Posted on by RobbertMeijer 40

Hi!

We have an ODATA set-up for an instance, but we get an error when connecting to it via the webbrowser.

Below is what I can see in the event viewer.
Any idea?

RootException: NavODataServiceUnavailableException
The session could not be retrieved from the server. The application will close.

    What is the error you are getting in Web browser? Are you using Web service Key with Basic Authentication?

    I get the following error in the webbrowser:

    {"error":{"code":"Application_ServiceUnavailable","message":"The session could not be retrieved from the server. The application will close.  CorrelationId:  702fd6fa-b4d0-4252-817b-1dd3ba8c1."}}.

    I'm using type Windows as credential type. I've tried to use NavUsePassword, but with no luck. Same error.

    Hello,

    1- Please check if  OData service is enabled.

    2- add Odata port to firewall or stop the firewall on both server and client.

    3- Enable "Use NTLM Authentication" in the administration console and restart the service.

    Hi Hassan!

    Unfortunately, all of the above things didn't work.

    Hi Robberto,

     

    Have you tried logging in using the basic authentication?

     

    Basically you need to setup first web service key at your user, then to login using the web browser you need to use username and web access key.
    docs.microsoft.com/.../web-services-authentication

     

    It should resolve your issue.

    Keep in mind that the above authentication method will be deprecated soon as we will use OAuth 2.0

    Do you have multiple NAV instances running on the same server?

    I fixed it with the below command inside the shell:

    Start-NavDataUpgrade -ServerInstance <ServerInstanceName> -FunctionExecutionMode Serial -ContinueOnError
