SmartThings could not validate the webhook URL

[chrwei]

The problem

When setting up Smartthings after entering the access token I get the error "SmartThings could not validate the webhook URL. Please ensure the webhook URL is reachable from the internet and try again.". the logs show this timeout error, but the error comes immediately, less than 2 seconds, it doesn't feel like a timeout.

I have done the curl -X lifecycle PING from an external linux host and it succeeds. I have tried adding the debug log config yaml, but it has no change, I'm guessing because the error is from configflow? I also do not have a .storage folder.

Additionally, if I put the callback URL into a browser on an outside host, I do get the expected "Webhook only supports PUT,POST methods but GET was received" error, so I believe my ssl and external access is working fine.

Additional information

My home assistant OS is running as a virtual machine on a Synology NAS, and https to http reverse proxied via Synology's such that Synology handles the SSL cert. I'm also using ducknds DDNS. The HA Android app on cell data and Google's Assistant connections work via https without issue.

Do i need to provide more info? what info is needed?

[omerfaruk-aran]

I'm experiencing the same issue exactly as chrwei described. The only difference is that I'm using DNS and SSL through Cloudflare. This way, I can establish a smooth connection both on mobile and in browsers. Moreover, my integrations with Amazon Alexa work flawlessly with this SSL. My operating system is installed on RPi 4 8GB, and the system details are as follows:

[omerfaruk-aran]

I solved the problem. As a solution, I uninstalled and reinstalled cloudflare and connected with the automatic auth method, then the addition was successful.

[prnzngr]

I have exact the same issue with Cloudflare. Reinstall didn't help.

Any Idea?

I have also been trying to link SmartThinks for days but am having the exact same problem.

What I do notice, no idea if this affects link creation, is that when you click on the SmartThinks API url from the token page, you get the error message: 503 Service Temporarily Unavailable

This link points to this url: https://smartthings.developer.samsung.com/develop/api-ref/st-api.html

TargetTimeoutError is what the ST API indicates when it can't connect to the webhook endpoint for any reason. If it's failing immediately, it's likely a certificate or SSL configuration issue. Check the notes in the documentation, particularly step 3: https://www.home-assistant.io/integrations/smartthings#webhook-troubleshooting-checklist

Hello,

You can resolve the issue by following the steps in the video linked below to install Cloudflare. Before installing it, you may need to reset the configuration.yaml settings. If Cloudflare is already installed, you should uninstall it, restart the system, and then proceed with these steps. After installing Cloudflare, restart the system and proceed with the SmartThings setup.

Your tipps dont resolve this issue.

[Martijn085]

My current configuration has a webserver on a raspberry pi with a reverse proxy configured with Nginx.
I have tried all possible settings but after days of testing it has not worked yet.

Finally I found a temporary solution that still adds the SmartThink intergration correctly.

Install the NGINX Home Assistant SSL proxy add-in and configure it with your own (already active) domain and open port 443 to Home Assistant.

SmartThinks can now be added (with the same certificate I already had active) to Home Assistant using the webhook.
I then reset the port to my web server after which SmartThinks continues to function without problems.

[prnzngr]

No. I won’t open a port. Every other Cloud Integration is working without opening a port like Tado, Gardena, Alexa, Nuki, BMW, Ring and so on. So the Devs should get this working without bothering the users

[andrewsayre]

Sorry y'all are having issues configuring the prerequisites for this integration. I'm closing this thread as there isn't an issue with the integration in HA and GitHub is not a support forum.
