Crash report upload timed out.

Error message

Crash report upload timed out.

What it means

If the crash-report upload finished with zero successful landings and no recorded exception, ThrowIfNothingLanded reports it as a timeout: no part of the report reached the server within the allowed time.

Solutions

1. Retry the upload (or leave the run directory for a later session's retry)
2. Check network/proxy configuration for silently dropping firewalls
3. Increase the upload timeout budget if the environment is slow, or send reports asynchronously at next startup

Example fix

// before
await sender.SendAsync(report); // blocks shutdown on slow network
// after
try { await sender.SendAsync(report); }
catch (IOException e) when (e.Message.Contains("timed out")) { /* defer to next launch */ }

// pre-check endpoint reachability before attempting upload
using var ping = new HttpClient { Timeout = TimeSpan.FromSeconds(5) };
var reachable = await ping.GetAsync(dsnEndpoint) is { } resp;

try { await sender.SendAsync(report); }
catch (IOException e) when (e.Message.Contains("timed out"))
{ /* schedule retry at next startup */ }

When it happens

Trigger: SendCoreAsync completes but succeeded == 0 and failure == null — all upload attempts neither failed explicitly nor landed, typically because requests exceeded the timeout window or were abandoned.

Common situations: Very slow or partially blocked networks; firewall silently dropping packets instead of refusing; an unreachable Sentry endpoint where connections hang rather than error.

Understand the failure class

Background: Request timed out: what client-side request timeouts mean across libraries (Request timed out, TIMED_OUT, APITimeoutError) — this error's family across 39 libraries.

• Timeouts: ETIMEDOUT, deadlines, and hung requests — what actually expires when a request times out.
