If you have uploaded the esphome firmware to the device, and it is correct, then it is more than likely a network issue.
If you'd care to post you code I'd gladly take a look at it for you.
Did you use ESPHome to upload it? If so, you'll have seen the 'finished message. From there you should be able to see the log. Can you see it?
