Microsoft.Azure.NotificationHubs.GetInstallation ends in timeout

I have updated from Microsoft.Azure.NotificationHub 3.3. to Microsoft.Azure.NotificationHubs 4.0.0.
Before that my .Net-Backend worked fine!

But now I receive a timeout, when I try to get the installation by calling:

installation = Startup.hub.GetInstallation(installationId);

Has anyone a solution for this problem?

kind regards,

Hi @MartinStein-9442,

Did you create two separate repos for the issue where it works in 3.3 consistently and not at all in 4.0? we would like to know the consistency of the timeout if it is always versus it has happened sporadically.
