# [Blazor] each navigation to external logs 2 errors a minute later

Capture an exception and log a message when navigation fails because the session has ended.

## Description

- The user clicks the link to the target URL.
- That link is intercepted in the JavaScript.
- .NET is called to determine if navigation to the URL needs to be prevented.
- It is determined that there is no need to prevent navigation and "navigateTo" is called via JS interop in NavigationManager.ts.
- The URL is determined to be external by "navigateTo" and the location is set to the new URL.
- The unload event in the browser is automatically triggered, which in turn triggers the call to _disconnect.
- As a result, the promise to "navigateTo" never completes (the page gets unloaded before that) and the associated task in .NET ends up getting cancelled with a timeout.

Fixes #45267

## Customer Impact

Customers see a large number of errors in their logs when their sites contain links to external sites, which in turn can trigger alerts in their incident monitoring systems.
