Problem is already stated in the title. 1Password does not fill in the second factor for ccp.netcup.net. I have to manually open the login in the extension and copy the TFA token from there. If it is important: I have multiple logins saved for that page. But this works fine on other sites like cloudflare.com, so I don't think that this might be the cause..
I have attached a field export from 1Password and the HTML source code of the TFA page: https://drive.google.com/drive/folders/1qEDwCDdPhSkkTxUeWqEjLd4dxQvOV8Mw
