SmartThings could not validate the webhook URL.

The problem

SmartThings could not validate the webhook URL. Please ensure the webhook URL is reachable from the internet and try again.

I'm using Cloudflare to open my homeassistant to the internet. The URL is available from the internet. SSL/TLS is valid (generated by cloudflare)

This command:

curl -X POST https://{EXTERNAL_URL}/api/webhook/{WEBHOOK_ID} -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"}}'

works with EXTERNAL URL output:

{"pingData": {"challenge": "00000000-0000-0000-0000-000000000000"}}

No its not my firewall I have modified it to pass the required IP addresses.

Hello, same error here. with HA 2024.3.3

I solved my problem reported above. In my cause it was caused by TLS/SSL validation issue.

First I checked on https://www.digicert.com/help/. It said my TLS chain could be not totally trusted by everyone
I found this https://phoenixnap.com/kb/install-ssl-certificate-nginx which pointed me out to the right direction: creating a crt bundle, merging SSL domain certificate and intermediate + CA certificate in a single fullchain.pem cert file
I updated fullchain.pem file on my HA and rebooted
Smarthings registration could be finally be completed!

Hope it could help someone else.

hey, i had the exact same issue. My HA setup is protected by Cloudflare with full TLS Offloading. I solved the issue by "downgrading" the security from TLS 1.3 only to TLS 1.2 accepted. It solved the issue.

It seems that the TLS implementation is to be explicited quite a bit : fully trusted certification chain, and TLS 1.2 compatibility. Might be related to samsung service i guess ...

hope this will help

I checked my website on n https://www.digicert.com/help/. I

All green check boxes.

I have Cloudflare managing SSL but I am exposing the service through Argo Tunnel
I have confirmed that I turned off TLS 1.3 support
I have checked with DigiCert and confirmed that the cert is in good standing however it complains that the cert was not issued by it. It also does not show TLS 1.3 support.
I confirmed that I can ping the webhook with Insomnia and got the ping data back.

Same error as reported above, request is malformed

Edit: Found the problem for anyone also using Cloudflare. CF security was blocking every request that was being made to webhook and classifying the requests as Bots. This explains why I was able to make requests to it manually.

I also confirm the issue was Cloudflare Bot fight mode turned on under Security > Bots. Disabling it fixed the issue
