telegram: connect failed: %w

Error message

telegram: connect failed: %w

What it means

runConnection wraps any failure establishing the Telegram long-poll connection (getUpdates/bot setup) into a retryLoopError tagged as initial-connect or reconnect failure depending on whether the platform has ever connected. The wrapped err carries the underlying cause.

Solutions

  1. Ensure no other process/bot instance is polling the same token (409 Conflict)
  2. Check host network connectivity and proxy settings
  3. Rely on/configure the retry backoff loop; inspect the wrapped cause for the root error
  4. Re-verify the token if 401s persist
Defensive patterns

Strategy: retry

Try / catch

if err := plat.Start(handler); err != nil {
    var rle *RetryLoopError
    if errors.As(err, &rle) {
        slog.Error("telegram connect loop ended", "cause", rle.Cause, "err", rle.Err)
    }
    return err
}

Prevention

When it happens

Trigger: The polling loop's connection attempt fails — bot creation error, getMe failure, or first getUpdates error — before or after a previously successful connection (which switches the retry cause from initial to reconnect).

Common situations: Network flap while the daemon runs; Telegram returning 409 Conflict because another poller instance holds a long-poll; token revoked mid-run; DNS failure.
