Issue with NTP Server response

[jjx932]

Hello I keep getting a no response from the ntp server request. I have swapped out the server from time.google.com to time-a-g.nist.gov however it still returns a no response. Please advise. Using an ESP8285 IR board ESP-01M.

It's probably a DNS configuration problem. Can try substituting the IP address for one of those URLs and see if it changes things. Also post the full logs and your configuration

[jjx932]

attempted with different varying ip addresses of time servers but to the same result.

here are my logs from the serial monitor:

*wm:STA IP Address: 10.0.1.10

my configuration is this board v-v with a usb esp flash controller

Does your local IP address configuration make sense? What is your router local IP address and intended subnet

[jjx932]

my router's local address is 192.168.1.1

[jjx932]

should i change it to a 192.168.x.x type static ip on the device?

[mdhiggins]

So there's your problem, your DNS IP address is pointing to nothing and your local IP is on a totally different subnet, fix those things or your won't be able to communicate with any network

[jjx932]

is this the correct section to modify?

char static_ip[16] = "192.168.1.25";
char static_gw[16] = "10.0.1.1";
char static_sn[16] = "255.255.255.0";
char static_dns[16] = "10.0.1.1";

[mdhiggins]

No, its not modified in code but is set up using WiFiManager during the setup phase, no code edits should be needed

my gpio10 is quite difficult to get to as it is a daughter board soldered onto another, is there a soft way to reset the wifimanager? if not I will try tomorrow when i have my jumpers..

[mdhiggins]

You could change the configpin variable to a different pin and set that other pin to ground during boot

Line 40 and 47
