Unable to open NAV 2013 R2 web client

simaak

Hi there,

We are having a bit of trouble with our Nav 2013 web client deployment.

We have a 3 server setup, a sql server, a nav server and a web server.

When on the web server we can access the client if we browse via the server name in our browser.
So if I browse to http://it-web:8080/NAV_2013R2_LIVE/WebC ... fault.aspx is works ok, I get the correct landing page.

When on the webserverm, if I browse to the IP of the webserver http://it-web:8080/NAV_2013R2_LIVE/WebC ... fault.aspx or
http://127.0.0.1:8080/NAV_2013R2_LIVE/W ... fault.aspx, I get the error:

'A server error has occurred, and the content cannot be displayed. Refresh the page or open a new browser window.'

If I browse http://localhost:8080/NAV_2013R2_LIVE/W ... fault.aspx it works.

If I browse to the address, either via name or IP from any other server or pc on the network, I also get the error above.

Below is the error I get in the event viewer of the web server.

There is no event logged when we use the web server name in the url locally.
There are no events logged on the Navserver or the sql server.

Any help would be appreciated.

Hi,

In C:\Inetpub\wwwroot\DynamicsNAV71 you have a file: web.config

in this file you need config the correct URL and Navision instance, SQL Instance, database...

Please check this file and tell your configuration.

Thanks.

hi,

In server where you have installed the web Cliente aplication, if you go to:

http://localhost:8080

Can you see the navision site saying: "This is a container"

simaak

Hi k0n4n,

When I go to http://localhost:8080 on the webserver I see the below message:

This is the default page for the site container for the web site of the Microsoft Dynamics NAV Web Server Components. You are viewing this page instead of the Microsoft Dynamics NAV Web Client because the URL that you entered in the browser address bar is in a format that is no longer valid.

To view Microsoft Dynamics NAV Web Client, you must include the web server instance name for the web site in the URL, as shown in the following example:

<http>://<webserver>[:<port>]/<webserverinstance>/WebClient

Contact your system administrator to get the web server instance name, and then enter the correct URL in the browser address bar.

You can find more details about URL format here: Opening a Page in the Microsoft Dynamics NAV Web Client by Using a URL

Thanks again,

Simaak

Hi,

OK, this is correct, can you post a imagen of your web aplication on IIS for create de correct URL.

Thanks.

Regards.

Hello,

can you try to open IIS console and follow these two steps (in green) :


Hope this helps!
Best regards,

simaak

Hi,

Please find below the screen shots:



Note that I can access the Web client using LocalHost or ServerName, but not with the IP. This is only possible from the Web Server. If I try from other PCs within domain it doesn't work at all.

Thanks

Hi,

This error message indicates that you probably did not setup delegation as explained on this MSDN page:
https://msdn.microsoft.com/en-us/library/jj551742%28v=nav.70%29.aspx?f=255&MSPPError=-2147217396

The problem is that when a user connects to the Web client the web client does not know if this is valid user or not.
Hence you need to setup a delegation so that Web client can pass "users"/information to the NAV Server Service.
For that reason it works fine on the local machine but it does not work from other machines.

I hope this helps.
Thanks.

Hi,

Im afraid thats done too. We had pretty much checked all the configurations specified in MSDN.

Tahnks for the response.

Cheers

Hi,

Did you really create entries on the Active Directory as explained in the MSDN document ?
And you have all entries for
NAVSERVER and
NAVSERVER.corp

We had the same issue. When the delegation was properly set on the AD it started working.
So I am pretty sure that your settings in AD are probably not correct.

Another option that works is to select
"Trust this computer for delegation to any services (Kerberos only)"
when you setup delegation.

Thanks.

Hi,

I am not sure about the solution but this is an old method to the issues. Please give it a try -

1. On the Web Server Navigate to C:\Windows\System32\drivers\etc
2. Open File hosts in Notepad and move to end of file the last entry should be something like - # ::1 localhost
3. After that add a entry in the format as below -

TAB IPADDRESS TAB MachineName

*TAB Represent the Keyboard button.
IF MY IP Address is 10.10.10.10 and my host/machine name is x.acme.com then my entry will be -
10.10.10.10 x.acme.com

4. Save the file and test after that with IP Adress.

Let us know the results.

Hi All,

Thank you so much for all your responses. The problem was with the Internet Explorer compatibility. Upon adding the Server Name and the IP in the Compatibility View Settings (IE->Tools/Compatibility View Setting) the problem got resolved.

Thanks again,
