We integrate to various customers QlikSense hubs but has lately experienced a little problem with that. We have a function for testing connectivitye to the client and this is how we found the problem. We can test the connection 5 times and it works fine and responds successfully. However, on the 6:th call we always get an error response and connection fails. If we wait a couple of minutes we are able to connect again. I suppose this is due to som limitation in the client setup only allowing a certain number of active connections? We call QlikSense by using the C# nuget package and all that code is within usings so it should be disposed correctly. Are we missing some best practice to close our connections or is this something that needs to be fixed on the clients setups? Other clients do not have this problem.
You are more than little running into the sessions limit of 5. The normal behavior would the after 5 connections the 6th one will fail. You should be able make another connection after 6 minutes. If this is the case it's working as designed.
