SmartThings - The request is malformed

[bakerbug (Bill Baker)]

I’m trying to set up the SmartThings integration. When I go to enter my access token, I receive the error:

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

Thing is, I’m using Nabu Casa. So I’m pretty sure the webhook URL is right. This is confirmed by the fact that I get an exception in my HA log whenever I try to submit the access token.

Here is the exception I see:

I’m running HA 111.1. Anyone have any ideas what may be going on?

[bakerbug (Bill Baker)]

Any ideas? I’ve been stuck here for a few days now.

[bakerbug (Bill Baker)]

In the conifg/.storage directory there is a file called smartthings. I renamed this file, rebooted HA, then tried to re-add the SmartThings integration. This generated a new Nabu Casa URL, and I was able to successfully add the integration.

Not sure what happened with the original, but blowing that file away and starting over resolved my issue.

Didn’t work for me. new install, well I’m trying to install.

There does not appear that anyone is following this post and I’ve seen no fix anywhere. Even the post found do not seem to have a clear answer and I’ve tried them all with no success hoping someone can assist here. Thanks

Thanks. That worked for me. I spent hours figuring this out

[celindho (Christian Lindholm)]

I’m having this very same problem, did you find a solution?

[daveco (David Cooke)]

no very frustrating.

It might be the TLS config. Check this post.

Webhook for smartthings not reachable

Replying in case someone is googling this If you get the same issue as above, it’s very possible that Samsung Smartthings cannot reach your homeassistant instance due to your TLS configuration. Most probably you are using lets encrypt. What worked for me is, I changed the nginx configuration to use as ssl_certificate the full chain fullchain.pem, rather than just the cert.pem. While you’re there, don’t forget to disable TLS v1 and v1.1!

Check your ip_bans.yaml! Try removing anything in that file and restart Home Assistant before trying to add the integration.

Somehow the smartthings servers got banned in my case and that led to the error message with upstream status code=403 showing up.

Took me ages to find that out.
