Yes, it works fine - although I’m not running any Blynk specific code on the devices I use for HTTP updates.
I know that most people who use it with Blynk tend to have an Update button widget that they use to trigger an HTTP update.
Are you having problems with Blynk interfering with the HTTP process, or you just can’t get it working?
Have a read through this thread:
It explains what I do using a free web hosting account. Maybe try getting it to work with some simple code while the device is connected to the serial monitor, so you can see what messages you’re getting and get to the point where you’re confident that the HTTP update is working before trying it with Blynk?
When I was testing I had my code wait 30 seconds after booting up before it started an HTTP update, nice and simple and with plenty of serial print messages dotted around so I could see what was happening.
