I need more information, can you answer my previous questions?

  • Which board are you using?
  • How are you powering your ESP board?
  • Are you using my exact code?
  • What’s the circuit that you have connected?

Connecting a load to a relay shouldn’t cause any error like that…

Are you using my exact code and schematics? Just because I can’t see exactly what you’re doing which makes it very hard to debug or help with your project.
Can you power your ESP with an external power supply?

To be honest, I’m not sure why it’s not working for you. Based on that information, it seems that you are doing everything right…

Does 5V relay work for 3.3V

To power the relay module? If the module operates at 5V, you should power it with 5V. However, to control the relay the 3.3V signal from the ESP should work just fine.
