You are running build 5.54.1026.1. Please download the recent build from our Web page (or from NuGet), verify that is is 5.54.1151.1 or later, re-build your project with it, and re-test.

Session closed / lost connection when item refresh every 35 minutes was created by scaglio

Hello, I have problems using EasyUAClient to read items that refresh after a long time period. I'm using quick opc UA client to monitor a sinumerik opcua server. The ''piece done' counter refreshes in about 35 minutes. The problem is that easyuaclient session at that time seems to be closed or something like that, and the client is stuck (If I shut down/restart opc server the client does nothing).

Using a opcua emulation server (Prosys) I have been able to reproduce the problem. If an item refreshes quickly, non problems found.
I'm using version 2018.3.
I attach quick opc logs.
Best Regards.
