Home Assistant error: "Cannot connect to host 127.0.0.1:63188 ssl"

I’ve got an error at Home Assistant start:

Logger: homeassistant.components.esphome.dashboard
Source: helpers/update_coordinator.py:215
Integration: ESPHome (documentation, issues)
First occurred: 21:03:42 (1 occurrences)
Last logged: 21:03:42

Error requesting ESPHome Dashboard data: Cannot connect to host 127.0.0.1:63188 ssl:default [Connect call failed ('127.0.0.1', 63188)]

What does it mean?

Did you fix this?

I have the same problem.

Check your firewall, i fix using:

sudo ufw allow 63188

Hi. I have the same problem. Which firewall you mean? My router? Where to I run the sudo command?

In my case at server, Ubuntu terminal.
