Not Working after a while

[JacopoLucky]

I have some strip connected with an ESP01. The first two days they worked normally, I have also tested it with the app. Now It seems like nothing is received by the ESP, the FPS counter shows 0 FPS, but I've checked the IP and the port and it is correct. Any guess on the problem?

Did you check the IP of both devices? Sometimes DHCP will renew the lease on a device and give it a new IP after a while. try giving it a static IP in your router settings.
