NAV 2017 integration to Dynamics 365

Hi,

I am trying to setup integration between our NAV 2017 and Dynamics 365 instance.

However, whenever trying to use the Microsoft Dynamics CRM Connection Setup assisted setup wizard within NAV I am receiving the error "An existing connection was forcibly closed by the remote host".

NAV Version: 9.1.0000.15635

Dynamics 365 Version: 10.0.13682.0

Is this a common issue and do you have any suggestions what may be causing the issue?

If any further information is needed before a suggestion can be made please let me know, thanks in advance

Thanks

Danny

Hello,

I am pretty sure that this is related to Tls1.2. Since your customer is running a very old build of Dynamics NAV 2017, you must upgrade to later / later CU but at least this CU:

Thanks.
