I’m connected to ESP-WROOM device from a PC on Windows 11. I’m trying to connect a socket in MicroPython to a server on my LAN.

I simplified my code to the following to show the error I keep getting.

import socket
import network

wlan = network.WLAN(network.STA_IF)
if wlan.isconnected() : print('Connected') 
tgt=(('192.168.1.90',50000))

s=socket.socket()
s.connect(tgt)
print('Done')
type here

The result when I run:

MPY: soft reboot
Connected
Traceback (most recent call last):
File “”, line 9, in
OSError: [Errno 104] ECONNRESET

Line 9 is the s.connect() line. I’ve seen many examples that suggest this should work.

Why do I get this error?
