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
- Ensure no other process/bot instance is polling the same token (409 Conflict)
- Check host network connectivity and proxy settings
- Rely on/configure the retry backoff loop; inspect the wrapped cause for the root error
- 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
- Run a single poller per bot token (avoids 409 conflicts)
- Monitor host network stability; use a proxy with sane timeouts
- Let the built-in retry/backoff loop handle transient failures
- Alert on repeated reconnect failures rather than crashing
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.
