Lost connection to Home Assistant

I have been sending my emonpi data to Home Assistant for several years now. Last night I was working on setting up a new integration in HA when suddenly HA stopped receiving data from emoncms. I found this error log:

Logger: homeassistant.components.emoncms.sensor
Source: components/emoncms/sensor.py:285
Integration: emoncms (documentation, issues)
First occurred: 13 December 2023 at 19:34:59 (1 occurrences)
Last logged: 13 December 2023 at 19:34:59

HTTPConnectionPool(host='', port=80): Max retries exceeded with url: /feed/list.json?apikey=858xxxxxxxxxxx4a8b (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7f728ca110>: Failed to establish a new connection: [Errno 113] Host is unreachable')) 

I hadn’t touched the configuration.yaml file but here it is:

# emoncms
  - platform: emoncms
    api_key: 858axxxxxxxxxxc4a8b
    id: 1

Any ideas please?

…oh and I did check that the url is still correct and I am able to get into emonpi using that.

Have you changed anything else in HA such as SSL, VPN or the likes?

I have an oddity that suddenly my node-RED add-on cannot use the HTTP node for an external site. I think something may have changed internally in HA. My emoncms component is fine (HA version 2023.11.x)

I didn’t do anything but it seems to be working fine now. Thanks for answering.

Ok, local connection issues. It does happen.
