Unable to setup Home Connect - fails with client or redirection URI not authorized

[vk2him]

The problem

I've had the Home Connect integration working for a long time - today it stoped working and when I try to reinstall I get this error which opens in a new tab:
{
"error": "unauthorized_client",
"error_description": "client or redirection URI not authorized",
"state": "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJmbG93X2lkIjoiOTI5MzE3OTBiMWQ1ZmJlNzEzODY5NjEzMTFjNTVkMmEiLCJyZWRpcmVjdF91cmkiOiJodHRwczovL215LmhvbWUtYXNzaXN0YW50LmlvL3JlZGlyZWN0L29hdXRoIn0.jua7oFgTTopLEGqsDWoEAg5dDpcaHam6QMtB9joNGU8"
}

I tried creating a new Application in the Home Connect Developer website but it fails with same error

Hey there @DavidMStraub, mind taking a look at this issue as it has been labeled with an integration (home_connect) you are listed as a code owner for? Thanks!

Can also confirm same issue. I had a working setup about 1 month ago, but did remove it to add again because of troubleshooting some other issues, and its no longer possible to setup.

[NewsGuyTor]

Same issue here.

[filzer666]

Same here, trying for days now :/

@allenporter Mind taking a look at this issue as you have been working on the new application_credentials platform integration (#71988)?

[allenporter]

Hi -- see updated pre-reqs in https://www.home-assistant.io/integrations/home_connect/#prerequisites and https://www.home-assistant.io/blog/2022/06/01/release-20226/#streamlining-the-oauth2-experience -- in particular the redirect url was changed.

This is not related to application credentials, but generally i have been helping home connect users and in all cases we've seen before issues have been due to misconfiguration or needing an updated configuration.

[allenporter]

(I don't have a home connect device, but did sign up for the developer program and tested it all out etc so my help can only go so far)

[jarrah31]

I had the same problem - my redirect url within Home-Connect's Application site was pointing to a local IP, so I changed it to https://my.home-assistant.io/redirect/oauth as described in the prerequisites and it worked for me!

[jarrah31]

@allenporter thanks for all your work on OAuth2 and for making things easier to use with HA - much appreciated!

I've probably just missed something but after removing my old Home Connect integration (was very buggy) I tried to set it up again but are running into this exact problem.

I've tried with the new my: and the new link but what ever I do I get the same error "client or redirection URI not authorized".

Is there something else that has changed that I need to adress?

[allenporter]

The redirect url was updated and you are not meeting the pre-requisites specified here https://www.home-assistant.io/integrations/home_connect/#prerequisites -- those steps talk about setting it up, but the steps for editing the url are:

• Visit https://developer.home-connect.com/applications
• See your application under `Your Applications
• Click Edit
• Change Redirect URI to https://my.home-assistant.io/redirect/oauth and save

[ZyberSE]

Thing is I've done that. Is there anything else that have changed?

The two things that changed are:

• The redirect url
• How credentials are stored (moved from yaml to UI) https://www.home-assistant.io/integrations/application_credentials/

Do you have multiple applications setup? Maybe re-setting up on the application credentials side? https://www.home-assistant.io/integrations/application_credentials/

That's it, I removed those and it works now. Thank you.

Helped me too. Removed both, restarted HA, and run setup again; browser asked for popup after which it 'stuck' again saying again that redirection uri not authorized.. -> restart HA once more hoping it will then ask for singlekey ID login and it's consent and it did..

[allenporter]

Double check the oauth credentials redirect UI to point at the exact url specified (my home assistant etc not your actual instance)
