NAV 2017 can't access WebClient, receive "A server error has occured..."

MarcusRB

Hello,

I have been trying to setup and access the NAV 2017 WebClient, and I've run into an issue that I can't get past.

I followed the following guide (except step 2, 3 & 4 as I'm using Windows authentication): https://saurav-nav.blogspot.dk/2015/11/microsoft-dynamics-nav-2016-how-to.html

I'm currently receiving the following error when trying to access the WebClient:



I get this error when accessing it locally and from another computer in our domain, it also doesn't matter whether I use Internet Explorer or FireFox.

This is the logged error in my event viewer:

Fejl under adgang til webstedet Microsoft Dynamics NAV 2017 Web Client

I'm not using the default NAV server instance, but one that was created by our (very capable) technical team,- I added a NAV webserver instance using the following command:

New-NAVWebServerInstance -WebServerInstance NAV2017UDV -Server XXXXX -ServerInstance NAV2017UDV -ClientServicesCredentialType Windows

I confirmed that it was created by opening IIS (it's on the same server as NAV).

I have had a look at the following MSDN page: https://msdn.microsoft.com/en-us/library/hh997105(v=nav.90).aspx
And I can cross off all checkpoints.

EDIT: I am able to log into the Windows client just fine.

Best regards

Did you provide client port as well?

Do you mean in the URL? As in e.g. "https://localhost:7012/XX/WebClient"?

If I add port number in the URL I can't even get the loading page.


EDIT:
If I use "https://localhost:8080/XX/WebClient&quot; I get the following error:

mohana_cse06

you need to use correct port no. in your webclient config file also.
please check web client config file.

can you translate above error to English?

I tried changing the default port 7046 to my "Client Services" port 7012, but there was really no change.

Translated error:

An error occurred during a connection to <server-name>.
SSL received a record that exceeded the maximum permissible length.
(Error code: ssl_error_rx_record_too_long)

same for me, anyone else helping here?
