Brilliant, thank you. That appears to have done the trick in 2018.1 as well.
Many Thanks!

Thank you for reporting this.
This appears to be a bug on our side. We will fix it in version 2018.3; below is a workaround (tested with 2018.2).
Place the following XML snippet into the UA SDK configuration file, as sub-element of <SecurityConfiguration>:
I hope this helps
Best regards

I've given the AppConfig UAConfigurationSources a shot but am seeing a different error with the ReadMultiple call now; specifically "Attempt to add existing item into a set." when the code hits:
ValueResult[] readResults = client.ReadMultipleValues(readNodes.ToArray());
I've switched to version 2018.1 to see if this might help but the behavior is the same.
I am using the config.xml file you linked to here www.opclabs.com/forum/ua-reading-writing-subscriptions/1781-...re-than-1-minute?start=10#3952 without any modifications. (just the name of the file)
The app.config file now contains:
ValueResult[] readResults = client.ReadMultipleValues(readNodes.ToArray());

Hello,
this will probably be the OperationTimeout which is not not yet configurable by the parameters, but by a different procedure.
See opclabs.doc-that.com/files/onlinedocs/QuickOpc/Latest/User%2...plication%20Configuration.html .
And some related old posts e.g. Best regards

Possible Session Timeout before SessionTimeout is hit was created by Holbach
I am currently using version 5.23 and targeting Framework 3.5. I have a collection of about 2000 UAReadArguments that are being read in a single transaction - the read can take a LONG time to complete - 5+ hours - so I am looking for ways to increase the timeouts the EasyUAClient is using.
I've tried increasing all timeouts I was able to find, but am seeing the EasyUAClient send a Close Session request after exactly 10 minutes and 6 seconds (watching the traffic in a Wireshark), and I am catching a BadRequestTimeout - is there a timeout I am missing, and the session is being closed as a result (instead of being the cause of the timeout)
This is not the exact code being used, but is the same where it matters:
client = new EasyUAClient();
client.Isolated = true;
client.IsolatedAdaptableParameters.Session.CloseTimeout = 120000000;
client.IsolatedAdaptableParameters.Session.SessionTimeout = 120000000;
client.IsolatedAdaptableParameters.Session.SessionConnectTimeout = 120000000;
resultList.Add(client.ReadMultipleValues(readArray));
