Authentication issues (Something went wrong)

[oversc0re]

Hello!
First thanks for the great effort to the author! I have come across a similar issue here #216, but as the discussion is closed, I am creating a new one here. Please let me know if that is not the preferred way.

I am stuck in this "something went wrong" loop and am unable to get past it.
When the Daikin web page opens for authentication, I am presented with this screen:

Observing that page URL https://id.daikin.eu/cdc/onecta/oidc/registration-login.html?error=true&mode=error&clientID=ijrSHwuRtV9eHdlgU48KbwcY&message=The+redirect+URI+in+the+request:+https://mydomain.eu/auth/external/callback+did+not+match+a+registered+redirect+URI.&code=invalid_request&skipConsent=false
indicates a mismatch between my URL and the URL registered on the Daikin developer portal.
I have tried using https://my.home-assistant.io/redirect/oauth as well as https://mydomain.eu/redirect/oauth as a redirect URI, but it does not work either way.
In the description it is not entirely clear whether i need to put that URL into the redirect field or should use this URL to generate a correct redirect URL. In first case, I don't understand how my.home-assistant.io can be linked to my domain. In the second, I tried doing that but it failed with the same result.

Any help would be appreciated.

Thanks!
Matic

First step to try is to use https://my.home-assistant.io/ as URL in your browser, does that show a web page, if yes, use https://my.home-assistant.io/redirect/oauth as redirect URI when creating the application on the daikin portal

I am trying to intergrate this from July and it always as many in here return me the (something went wrong) message.
In my case in (https://my.home-assistant.io/redirect/oauth) i wasnt write (my.home-assistant.io) as it is, i was writting my really Home Assistant address.
Tonight i tried again with (https://my.home-assistant.io/redirect/oauth) AS IT IS and voilà...!!!
I managed to successfully intergrate Daikin Onecta.

Thank you! I had the same problem since July and it works with the given url. :) merci !

Thanks for the feedback. I still think I am doing everything as instructed, though it isn't working.
Going to https://my.home-assistant.io/ i am prompted with a page that includes a link to my domain which is correct. Clicking on the link I land on my homeassistant page:

Using https://my.home-assistant.io/redirect/oauth in Daikin developer portal

Double checked the tokens, but I am still receiving something went wrong.
I am trying to think if there is anything different from an average setup, but I can't think of anything. I am using a domain and homassistant is bound to default ssl port (443).

Also tried deleting the application and HASS credentials and restarting from scratch but it did not help.
If I try connecting when the application in the developer portal is deleted, the error is different https://id.daikin.eu/cdc/onecta/oidc/registration-login.html?error=true&mode=error&clientID=ijrSHwuRtV9eHdlgU48KbwcY&message=The%2Bclient%2Bwas%2Bnot%2Bfound.&code=unauthorized_client&skipConsent=false from which I assume there is obviously something wrong with the redirect settings.

Try a different browser

Tried incognito window, different browser and a different computer but it always fails the same way.

I will try authenticating manually, but I need to read the docs to see what should be included in the post request.

See https://developer.cloud.daikineurope.com/docs/b0dffcaa-7b51-428a-bdff-a7c8a64195c0/business_validation for the Daikin contact details, maybe they can see what is going wrong with your account

I finally cracked the problem.

The main reason was that forwarding via https://my.home-assistant.io/ only works if default_config: or my: is enabled in configuration.yaml. If not, forward to the domain works, but underlying redirect paths return 404.

I ended up using https://mydomain.eu/auth/external/callback rather than https://my.home-assistant.io/redirect/oauth as I find it more reliable.

Thanks for the support and an awesome plugin!
