could not connect to MQTT server OSError-202

[davefes]

I have been running Mike Teachman's pubishThingspeak.py for several weeks on one cell network, using a ESP32. I tried another cell provider and I got the above error. Also, I have tried on a fibre home network and it results in the same error.

Do some network providers prevent Thingspeak's MQTT server from listening on port 1883 to my device?

Thanks,

Problem solved

# connect the device to the WiFi network
wifi = network.WLAN(network.STA_IF)
wifi.active(True)
utime.sleep(0.5)
#wifi.ifconfig(('192.168.10.80', '255.255.255.0', '192.168.10.1', '8.8.8.8'))
wifi.connect(WIFI_SSID, WIFI_PASSWORD)

I had set the first unit up with a static IP, which I didn't change when going to the following routers. The units still said that it had connected to the WiFi but having that line still in probably confused the ESP32 :(
