Offline problem after several hours

Need Help With My Project
,
1

Hello everyone;
I have some issues about my new project. Im controlling four relays and using dht22 for humidity and temperature. Everything is good but after about 10 hours power on nodemcu, device goes offline and it doesn’t be online until I reset. Also device goes often offline and online in that 10 hours.

Details :
• Nodemcu Lolin V3
• I use Blynk server
• Blynk Library version is 0.6.1

I think that your void loop, and the sub-loops that are called from it, are the issue.
You should read this:

Pete.

Thank you so much for reply sir. I think thats the point, I will fix it.
