What type of account do you have (Free, Maker, Pro)?
If it’s a free account, when was it created?

Your code is very badly written, in quite a few ways.

Currently, your code does two Blynk.virtualWrites every second. This isn’t necessary, as you only need to change the status of V0 and V1 if they change, not once per second regardless of whether the value has changed.

The latest version of the Free subscription is limited to 30,000 messages exchanges between the server and all of your devices combined, every month.
The way your code is written, you would exceed that limit once your device has been online for 250 minutes (just over 4 hours).
I believe that the web console has a status bar which tells you the current message count.

Also, you shouldn’t use delays in your sketch, you should use BlynkTimer instead, and your void loop should only contain Blynk.run() and timer.run().
