Need Help With My Project

I think you have a problem with the way that either the Arduino IDE or your associated libraries are installed. A fresh portable install on a removable drive would eliminate that possibility.

I guess that its’s also possible that one of these other things may be causing the problem:

  1. your wifi data to/from the Blynk server is being corrupted - either by your internal network or your ISP

  2. your NodeMCU could be faulty.

The first possibility could be tested by connecting to as different Wi-Fi network, or a hotspot created using your phone.

Pete,

Bingo!

I connected through my phone hotspot!

The blynk app connected and everything is working.

What do you suppose is the issue with my home wifi?

BTW, thanks so much you’re a star!

So, it’s either your internal network or your ISP that’s blocking the Blynk traffic.
You’d said earlier that the downloads of the Blynk core kept failing, so maybe it’s an internal network issue?
Start by rebooting your router and turning off any wireless repeaters/access points and working within close range of the router.

If you still have a problem then try a different router if you have one.

Pete.
