Hello,

Blazor server side question:
We have an app (.Net core 3.1) which is hosted on Azure.
When the app is not used for several minutes and user clicks in the app an error will occure in web console Error: Circuit not initialized., second click means Uncaught (in promise) Error: Cannot send data if the connection is not in the 'Connected' State. => Blazor is disconnected.

How it can happen that circuit is not inicialized?
I tried to increase DisconnectedCircuitRetentionPeriod to 3 hours but without any proggress.

Thank you in advance for help.

/David
