RESTFul Command sometimes starts failing, only restart resolves it

Configuration
1

I have couple of rest commands in my configuration:

rest_command:
  grenton_update:
    url: http://192.168.0.11/HA_Listener
    method: POST
    headers:
      accept: "application/json"
    payload: '{"type":"light", "object":"{{object}}", "state":"{{state}}"}'
    content_type: "application/json"
    verify_ssl: false
  grenton_update_cover:
    url: http://192.168.0.11/HA_Listener
    method: POST
    headers:
      accept: "application/json"
    payload: '{"type":"cover", "object":"{{object}}", "action":"{{action}}", "value": "{{value}}"}'
    content_type: "application/json"
    verify_ssl: false
  webhook_test:
    url: https://webhook.site/xxx-yyy-zzz
    method: POST
    headers:
      accept: "application/json"
    payload: '{"type":"cover", "object":"{{object}}", "action":"{{action}}", "value": "{{value}}"}'
    content_type: "application/json"
    verify_ssl: false

They work fine most of the time. However, sometimes they just don’t reach the target. I specifically added webhook_test to make sure it’s not something on the receiver side. The only way to make it work again is to restart the HA via Developer menu.

When HA fails and I run the same REST request from Postman it’s received by the target.

What should I do to troubleshoot the issue? Are there any logs related to restful command?

Any messages in the log?
