I have a really strange issue. My server is running on Linux using .NETCore 2.0 the client is Windows 10 and .NET 4.6.1 and I am using ServiceStack 5.0.2
After successful login I retrieve a couple of data which seem to work just fine. Than I retrieve one specific statistic record from MongoDB and this REST call gets a timeout and NEVER arrives at the server.
Now the crazy thing: If I set a break point in the client BEFORE the call gets fired, it works afterwards!!! I experience this since I am running .NET core, on Windows this never happened.
I switched from async to synchronous calls but no difference. I must say, that the server has many threads because I am using ServerSideEvents and Quartz which has a thread pool of a configurable size.
Here is some of my log-output:

bei BizBusLicenseManager.App.RefreshMessageStatistics(String username) in D:\Projects\BizBusLicenseManager\BizBusLicenseManager\App.xaml.cs:Zeile 134.
The code on the client is:
public void RefreshMessageStatistics(string username)
{
Logger.Debug($$"App.RefreshMessageStatistics({username}) entered");
try
{
var requestDto = new GetMsgStats4User
{
UserName = username,
};
var stats = LicenseServiceClient.Get(requestDto);
Logger.Debug($$"Received the following stats: {stats}");
SetMsgStats(new PushMessageStatistic4User(stats));
Logger.Debug($$"Message stats for user {username}: {MessageStats}");
UpdateMessageMenuHeader();
}
catch (WebServiceException we)
{
Logger.Error($$"Failed to get push message stats for user '{username}'. Exception: {we}");
}
catch (Exception ex)
{
Logger.Error($$"Failed to get push message stats for user '{username}'. Exception: {ex}");
}
}
If I set a breakpoint on the line Logger.Debug... it reaches the service on the server and returns valid data.
Can anybody give me a hint how I can track down this issue further, it is really strange…
Thanks a lot.
