I have the Passwords-APP running, but in the Logging i see the following error messages:
Error: idn_to_utf8(): INTL_IDNA_VARIANT_2003 is deprecated at /var/www/clients/client1/web1/web/apps/passwords/lib/Helper/Favicon/AbstractFaviconHelper.php#117
Error: idn_to_ascii(): INTL_IDNA_VARIANT_2003 is deprecated at /var/www/clients/client1/web1/web/apps/passwords/lib/Services/ValidationService.php#148

My system is:
Operating System: Linux 4.19.0-5-amd64 x86_64
PHP: Version: 7.3.27
NC 21.0.3

Has anyone an idea how i can fix the problem?

The app uses the idn_to_ascii function of PHP to validate domain names with the default settings for that function. In PHP 7.3 the default setting is INTL_IDNA_VARIANT_2003 which is at the same time also deprecated. (default = deprecated. that is confusing)
This is not really an issue and can safely be ignored.

If you want to fix it anyway you can either upgrade PHP to 7.4, patch the source code or adjust the error reporting settings of php to ignore deprecation warnings.
