Forum Post: Problem with Web Services from NAV 2013

Hi,

That we are able to publish Queries and Pages from NAV 2013 as Web Services is great. Sadly I have a problem that seems almost random. I have configuered the Dynamics NAV Server Instance for OData and published some web services from NAV and it works fine. But sometimes after a server restart or just a restart of the NAV Server Instance I get problem to connect to some of my published web services (also random, not the same web services every time). Then I need to restart the NAV Server Instance until it works and then it will work until someone restart the server or the NAV Server Instance again.

I currently have the problem with Version 7.0.35026.0. Does anyone know what the problem are? Is it a known bug?

Here is an error that I get in the eventlog when the web service doesn't answer:

Server instance: DynamicsNAVOData
