+### `Connection error` when logging in
+
+If you see "Connection error" when running `trigger login` (or "Failed to create authorization code"), try these in order:
+
+1. **Clear saved auth and retry:** `npx trigger.dev@latest logout`, then `npx trigger.dev@latest login` again. Sometimes an invalid config is cached.
+2. **VPN or firewall:** Disconnect from VPN or check firewall/proxy; try `npx trigger.dev@latest login -l debug` for more detail.
+3. **TLS / certificate store:** Node may use a different CA store than your OS (e.g. `curl` works but the CLI fails). Try `export NODE_EXTRA_CA_CERTS=/etc/ssl/cert.pem` (macOS/Linux) then login again, or reinstall Node so it gets updated certs. Behind a corporate proxy or custom CA? Set `NODE_EXTRA_CA_CERTS` to that CA file.

+### Realtime stream error (`sendBatchNonBlocking` / `S2AppendSession`)
+
+Errors mentioning `sendBatchNonBlocking`, `@s2-dev/streamstore`, or `S2AppendSession` (often with `code: undefined`) can occur when you close a stream and then await `waitUntilComplete()`, or when a stream runs for a long time (e.g. 20+ minutes). Wrap `waitUntilComplete()` in try/catch so Transport/closed-stream errors don't fail your task:
+
+```ts
+import { streams } from "@trigger.dev/sdk";
+
+const { waitUntilComplete } = streams.pipe("my-stream", dataStream); // or streams.writer(...)
+try {
+  await waitUntilComplete();
+} catch (err) {
+  // Transport/closed-stream; log if needed or ignore
+}
+```
+
+Alternatively, await `waitUntilComplete()` before closing the stream. See [Realtime Streams](/tasks/streams) for more.
