Description

As soon as you have lost contact with blazor.server.js, any transition to the links of the prejudice causes the error 'blazor.server.js:1 Uncaught (in promise) Error: Cannot send data if the connection is not in the 'Connected' State.'

I suggest in the absence of communication with the server to perform the usual transition by reference, without using server rendering. In this case, you do not need to display a window about disconnect, and the normal reconnection will be performed with the page reloading.

Contributor guide

Research direction
Investigate how Blazor Server handles connection loss during navigation. The suggestion is to fall back to standard link navigation without server rendering when disconnected. Look for the current navigation interception logic and the reconnection handling code. Modify the navigation to check connection state and perform a full page navigation if disconnected. Ensure no error is thrown and reconnection is handled on page reload.
