Link and relink returns error 404

[Plantje]

In my home I am using Google Home and Athom Homey. I noticed that the link between Homey and Google Home was not working. When I gave Google Home a command to switch something from Homey on or off, it would respond that Homey was unreachable.

So I tried to relink the accounts, by opening the Google Home app --> Add --> Works with Google --> search for Homey --> go through all the steps and then login to Homey. In most cases it returned a 404 HTTP error

I went to my Google account and there it was still linked. Removed the link there and after that I was unable to add it again.

After some trial and error currently I do see the Homey service linked in my account again, but if I go to the Google Home app and check the "Works with Google" services it is not there

In the Homey app, if I want to connect to Google Assistant it returns an error that I first need to link the accounts. Which is impossible

More important: tried relinking other "Works with Google" services and they all return a 404 error

When “Link and Relink” repeatedly returns a 404 error, it usually indicates that the system is trying to access a resource or endpoint that no longer exists or isn’t reachable. This can happen if the URL was changed, the file or page was removed, or your platform’s cached path is outdated. In many cases, simply updating the link to the correct current URL 3uTools or clearing old references resolves the issue. If you’re using an integrated tool or plugin, double-check its configuration, ensure the destination is still published or accessible, and verify that your permissions allow linking.

Thank you for your response. Let me see if I understand it. 

The problem is that I cannot link the Google Home and Athom Homey accounts. And also when trying to connect other services I often get the 404 error. But it seems to be a side effect

And to add: all devices from Homey are in Google Home. Yet they are offline and cannot be removed

The thing is: if I open the Google Home app and look at home.google.com, I see all of the devices:

Like with the "Koffiezetapparaat"

The one that is working is connected via Tuya. The other two screen shots are from one time where it looked like it was possible to link the accounts.

I think the issue lies in the following: if I unlink the accounts and remove as much as possible all devices still show in Google Home.

And in that case "Homey ontkoppelen" is greyed out (like in above screen shot) and if I click on it it displays: "Alleen de eigenaar kan het apparaat ontkoppelen"

So to me it seems that somewhere during a disconnect/unlink, the connection went down and now I have some uncontrollable devices.

Ok, got it fixed. Google Home and the accounts were a mess. Have removed my kids as admin from Google Home and that fixed the issue. Now I can rebuild.
