Error when setting up

[danbayliss]

Describe the bug

I'm having issues setting up the component. I've followed all the instructions and registered my address at my.home-assistant.io but when I click Link Account and it goes back to Home Assistant I just get a popup saying Error. My email address is all lowercase and I've tried my external and internal address and the same issue occurs. All my HC devices are working when I turn off WiFi on my phone.

The URL for the my.home-assistant.io screenshot is https://my.home-assistant.io/redirect/oauth/?code=eyJ4LXJlZyI6IkVVIiwieC1lbnYiOiJQUkQiLCJjcmVmIjoiOEYwNDlGRUIiLCJ0b2tlbiI6IjYwY2NiMzI0LWZiZjktNDA3Yi04NjkxLTI0NWVmYzIzZjY4MyIsImNsdHkiOiJwcml2YXRlIn0%3D&state=eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJmbG93X2lkIjoiMGFjZDI2YjFkODAzMDg1ZDJjNGRlODE3MzRjZDcyMTYiLCJyZWRpcmVjdF91cmkiOiJodHRwczovL215LmhvbWUtYXNzaXN0YW50LmlvL3JlZGlyZWN0L29hdXRoIn0.vhsVW2gv7LFIXiGFr7VW2iX5nahixS-2tIaMdocaoVM&grant_type=authorization_code

Same error here, with the same versions. I tried it several times, even created a new developer account to make sure the email address is all lowercase. Unfortunately, I can't get it to work.

These errors are always a configuration error. Please triple check you followed the instructions to the letter. Also, make sure you start the process from the same URL you finish in i.e. http://192.168.0.4:8123 If you still have an issue please post a screenshot of the Home Connect app you created.

I've double checked everything and it all appears to be correct. I have tried adding the devices using my internal and external address and always use the same URL at the start and on my.home-assistant.io. Here is a screenshot of my app

The configuration seems fine. Please make sure again that both the developer account and the Home Connect registered in your mobile app (the homeconnect@xxx.co.uk) are actually registered in all lower case. You can also check these cases to see how others have fixed this issue: #166 #207 #210

Changing my email address in the Home Connect mobile app solved the issue. So it doesn't matter how the email looks like in the developer portal, you need to check it in the app and make sure it's all lower case.

Based on the above I decided to login and change my address to see if it resolves the issue. On the mobile app my email address shows as homeconnect@xxx.co.uk but when I requested to change it, it comes up as Homeconnect@xxx.co.uk. I tried to change it to homeconnect@xxx.co.uk but it wouldn't let me so I changed it to homeconnect2@xxx.co.uk and then back to homeconnect@xxx.co.uk and it's now fixed
