Smartthings integrations error

Hi all, I know this is a common problem but all the topics i read doesn’t help me so i need help from you.
I’m trying to add my smartthings devices to ha but if i don’t use nabu casa ( with nabu works well ) I recived the error:

“SmartThings non è riuscito a convalidare l’URL del webhook. Assicurati che l’URL del webhook sia raggiungibile da Internet e riprova.”


	My token: xxxxxxxx-4929-4559-yyyy-3b6b4f8d5d65
	Smartthings Link:

If I open this link in the browser it shows:

405: Method Not Allowed


  ssl_certificate: /ssl/fullchain.pem
  ssl_key: /ssl/privkey.pem
  ip_ban_enabled: true
  login_attempts_threshold: 5

I do this Troubleshooting step:

1 - CURL

root> less /config/.storage/smartthings
   "version": 1,
   "minor_version": 1,
   "key": "smartthings",
   "data": {
     "instance_id": "f9dc10c3-4fa0-xxxx-yyyy-58b35a5f726f",
     "webhook_id": "b4a3d916ed66e8410ccccccccccccccccccccccbc8c0a1121b6fc4bfc12b202",
     "cloudhook_url": null
root>  curl -X POST -H "Content-Type: application/json; charset=utf-8" -d $'{"lifecycle": "PING", "executionId": "00000000-0000-0000-0000-000000000000", "locale": "en", "version": "1.0.0", "pingData": { "challenge": "00000000-0000-0000-0000-000000000000"}}'
 	curl: (60) SSL: no alternative certificate subject name matches target host name ''
 	More details here:
 curl failed to verify the legitimacy of the server and therefore could not establish a secure connection to it. To learn more about this situation and how to fix it, please visit the web page mentioned above.

TLS Certificate is not trusted
   The certificate is not signed by a trusted authority (checking against Mozilla's root store). If you bought the certificate from a trusted authority, you probably just need to install one or more Intermediate certificates. Contact your certificate provider for assistance doing this for your server platform.

I have this same issue with home assistant yellow and Nabu casa. I found this thread in my search for an answer. Still no luck.
