"Error" during installation of Miele integration

[Stefan28L]

I installed the integration by HACS.
I try to add the integration in HA which will start the configuration assistant.
I have already entered the miele developer information (ClientID etc.).
This takes me to the miele login page.
After i entered my login information it redirected me back to HA.
There i get the simple message-window "Error" which i can close with a "OK" button.

Now, every time i try to add the integration, i will see the miele login page, No longer asking for the Client ID.
I'm shure the login information itself is correct.

I find an error in my log file. Here is a smale cutout of the message:

Logger: aiohttp.server

After I deleted the credentials in home assistant and re-entered them, the connection works now.

@Stefan28L Where can you delete login details in Home Assistant? I entered the wrong token and cannot progress any further. I can't find that information anywhere.

Please look here: #247

Thank you for your quick response.
Just found the right file, which I could edit with editor 'nano' using the command below

nano /config/.storage/application_credentials

Be careful when you edit files in .storage/config . A mistake can easily crash your system.
