Error login dynamics web client 2013

Posted on by James Cervantes 145

Hi

We have installed Dynamics GP Web Client 2013 R2 on a web server computer. After successful installation of web client and check services running (GP Session Central Services, state: Running) we tried to login it given an error:

"There are no session hosts available for determining the most available session host in the farm. This error can occur if the session hosts are inactive or have reported that they cannot create any new sessions."

Can any one guide me here where i am doing wrong.

Thanks

    I did a login test and then saw the windows event viewer on both servers, but in the session host there are not any new message, only in web server (the same error listed below):

    Your session host server isn't aware of the session host.

    Can you take a look at the Windows Event Viewer on the session host and see if there are any messages?

    Do you have the self-signed cert installed in the trusted publishers section for both servers?

    I know when we have issues logging in with a new user its because the cert is installed improperly.

    You might want to check out Ian's blog on this. I didn't install a Scale-out solution. We have a small environment so it wasn't necessary to do a multi-tenant install. It was easier to put it all on one Web Server.

    Hi, yes, on my web server is running GP Session Central, and in the session host is running GP Session services.

    Just like Ian mentioned, do you have the following services running on your Web Server?
