Guess I read somewhere it could be fixed by removing the Mobile Homey App from your phone and re-installing.
Maybe have a option to try on another Phone?
or try connecting it from the Homey WebApp on a PC (Mac or Windows) from the Browser https://my.homey.app/
But that looks indeed like a bug.

What do you mean? you tried to add the Hue to Homey I guess?
Yes.
Try adding your Hue from the WebApp.
Done that also. Chrom brouwser, Chrome app and app on ios
Do you get the same Error ?
The same error happens every time
Sorry I have no Hue, I can’t test it now.

I was just installing my new Homey Cloud bridge and got the exact same error mentioned above when trying to add my Hue account.
Error: Client authentication failed (e.g., unknown client, no client authentication included, or unsupported authentication method).
I have the same Hue client authentication failed issue with Homey Cloud. I already reported it to Homey Support.
Hi i’m new to the forum and Homey too.
Got the same problem while adding HUE to my Homey cloud and reported it right away after trying the next things:
- different browers
- iOS app and web app
- I was logged into HUE bridge via gmail, deleted that too and logged in directly but didn’t help either.
- HUE bridge fully updated, fully reset, nothing works.
sidenote: I was only able to choose between the lightbulb and plug by adding devices, all other HUE devices did not appear.
same issue here, but am working with Homey Cloud in anticipation of receiving the Pro tomorrow. I was looking forward to homey pro, because it seemed the best option. But now I am not so sure anymore,… maybe I’ll return it… Or could it be it only works with a pro connected?
For the ones who are having issues with connecting the hue bridge to homey cloud, this is their response, I didn’t test it yet.
Response:
Hi Teun,
Thank you for reaching out to our support and I’m sorry to hear you’re experiencing issues with your Philips Hue devices on Homey Cloud. Our apologies for the inconvenience!
Our Development Team has looked at the issue and we found out that there were changes made in the authentication procedure without informing us, which is why you received this error notification.
We’ve updated the Philips Hue app, would you please be so kind to install the test version of the app on your Homey Cloud and could you please let me know if it resolved the issue for you as well?
Thank you for your cooperation!
I’m looking forward to hearing from you soon.
App should be updated by now for cloud users. I bought the Pro too this week and connecting hue bridge to the pro still works perfectly if they are in the same network.
yes, got that email as well today. Tested it and works
All the devices connected to Phillips hue is showing this error. I am using a Homey bridge. Started some time this week.
