I suppose that there is too many things on loop function.
Try to use BlynkTimer (AKA SimpleTimer) to launch periodically your check of data and your displayInfo function.
Then keep only Blynk.run() and Timer.run() on loop function.

You still have many things on loop, you didn’t change anything here…
Try to put this on another function and call it every 100ms or so with simpleTimer…

I guess that it is related to the shield that you are using is too slow, I had similar issues and use a ethernet shield instead the ESP8266 and was solve¡

if the ESP8266 works with AT commands and the workload is high, the systems stucks and take some time to reconect¡

hope to help you.

thanks so much. the problem is solved :rose::heart_eyes: I will never forget this grace

Update:

The problem is back but now after 1 hour disconnected from network

Did you try more times and always is disconnected at 1h?
are you using local server or cloud?
Are you using latest libraries?

Using cloud server

Yes I use 0.5.1 library
