core: Problem with user names containing spaces in Synology DSM

The problem

After upgrading from HA Core 2023.1.7 to 2022.2.0 or above I get the following error message for my Synology DSM integration: {‘api’: ‘SYNO.API.Auth’, ‘code’: 400, ‘reason’: ‘Invalid credentials’, ‘details’: ‘Invalid password or not admin account: Home Assistant VM’} 12:42:08 PM – (ERROR) Synology DSM Reauthenticating the integration is impossible.

When deleting the integration, I am unable to add it again. However, downgrading again to HA Core 2023.1.7 solves the issue. Please note that the credentials are correct and that Home Assistant VM is an admin account. This account has never caused issues before.

Could you please inform me if I am doing something wrong or how I can solve the issue?

I am running the latest version of DSM 6.2 with 2FA.

Thanks in advance.

Kind regards,

Robin
