• Most of my orders when using gateway swap command fail with node also in timeouts (expected since its a public node )
• Tested this with gateway swap and gateway lp ❌
• Tested with generic.arbtirage_controller

---

Note: When using a paid nodeURL, not able to reproduce this error ✅

Steps to reproduce

1. Setup development ver of both hummingbot and gateway
2. Use default nodeURL https://api.mainnet-beta.solana.com for testing jupiter/router
3. Run gateway swap command

Release version

dev-2.9.0
