My ESP32 Dev Board never connects to my TCP server, I know the WiFi works fine because HTTP client works. I can join to my TCP server from another computer. Both devices are in the same network and the IP & Port are correct. What can be the problem?
Firewall on server system??
Bad mac address??
with not seeing any code, hard to truly tell..
do you have a simple test sketch to present??
good luck.. ~q
I just used the TCP example from Arduino IDE ESP32 examples
could you server or the host operating system only be allowing connections from specific MAC addresses?
try running wireshark to monitor traffic?
