Dynamics 2017 Web Client

Posted on by Rumwood 5

Hi All

This might be a quick fix for someone who's done it before.

We have a Dynamics Nav 2017 middle tier server, running the required services for our Windows clients to connect to.

I've been trying to create a Web Client server, so have commissioned a new Server 2016 with IIS etc and done the installation.

From the server itself, logged on as a NAV user, the web client opens 100% and I can browse through the pages.

When connecting to the web client url from elsewhere on the same subnet, the page shows the logo and then "An error has occurred . . .".

The Application Event Viewer shows :-

Error accessing Website Microsoft Dynamics NAV 2017 Web Client
Raw Url: /Link_62/WebClient/list.aspx?spa=1&dc=0&inapp=false
Url: gclfweb02:8080/.../list.aspx
Type: Microsoft.Dynamics.Nav.Types.NavServerNotFoundException
Message: A server was not found at "net.tcp://gclfnav01:8046/Link_62/Service".
Either the URL is incorrect or the server is currently not available.

My question is - why, when I connect from a browser external to the web server, does the system add "\Service" to the url ?

I suspect this is why it's not working ?

Any ideas would be greatly received.

Thank you

    Hello,

    Then the link to the articles apply 100%. It is such a common question to Microsoft support.

    Thanks.

    Hi Marco

    No, by "external" I mean anything on the same subnet as the server which hosts the IIS and Web Client software. I suspect you have mis-read my post ?

    Using a browser on the same server as the IIS and Web Client, we connect to NAV 100%.

    Using a browser on any other computer, on the same subnet as the server, we get the error posted above.

    Thank you

    Hello,

    With external you mean outside the corporate network? Or just for a client machine that is hosted inside the corparate network. We recommend to use modern authentication when connecting from outside the corporate network, e.g. via Azure AD authentication.

    There are a few articles that must be followed very precisely:

    docs.microsoft.com/.../provision-server-account

    There is a Dynamics NAV article that needs to be followed as well very precisely and this article does apply to Dynamics 365 Business Central as well:

    docs.microsoft.com/.../walkthrough--installing-the-microsoft-dynamics-nav-web-server-components-on-three-computers

    Thanks.
