sessionState mode=”InProc”

Just wanted to share a silly mistake that I made when testing NAV 2016 web client (could have been any version).

NAV 2016 webservice error


When trying to access the webclient I got the above error (<sessionState mode=”InProc”/>).


I forgot to add the port number in the url. The webclient runs on port 8080 (default), but I didn’t specify this when typing in the url. I was trying to access instead of

The reason this has given me such a headache is that the url does exist, but the web client is configured for port 8080 which is why I am getting the above error.

I hope this will help someone else save some time 🙂
