Vaultwarden Support String

I've had SMTP with gmail setup and running fine with vaultwarden for almost 2 years. It has a;ways worked fine. Today, i noticed it stoped working.
My logs show this:

[2025-07-07 19:40:48.918][vaultwarden::mail][ERROR] SMTP 5xx error: permanent error (535): 5.7.8 Username and Password not accepted. For more information, go to5.7.8  https://support.google.com/mail/?p=BadCredentials ffacd0b85a97d-3b47030bd4dsm10815241f8f.7 - gsmtp - Authentication credentials invalid

[2025-07-07 19:40:48.918][vaultwarden::api::core::two_factor][ERROR] Error sending incomplete 2FA email: SMTP 5xx error: permanent error (535): 5.7.8 Username and Password not accepted.

I am using app passwords, and I even tried generating a new one, in case my original one somehow expired.

Here is the relevant part of my docker-compose:

      - SMTP_SECURITY=force_tls
      - SMTP_HOST=smtp.gmail.com
      - SMTP_PORT=587
      - SMTP_USERNAME=<redacted>@gmail.com
      - SMTP_PASSWORD=<redacted app password, with no spaces>
      - SMTP_FROM=<redacted>@gmail.com
