    The "System.Net.CookieContainer" throws an "ArgumentException" error when using a non-UTF-8 machine locale and hostname, as observed in various Unity versions on Windows 10 and Windows 11.

    To fix the ArgumentException error with System.Net.CookieContainer, ensure the hostname is in a UTF-8 compatible format. Change the hostname to avoid non-UTF-8 characters or properly encode it before use.

    To resolve the ArgumentException error with System.Net.CookieContainer, ensure that the hostname is in a UTF-8 compatible format. If the hostname contains multi-byte characters, like Japanese characters, it can cause this error. You may need to change the hostname to avoid non-UTF-8 characters or encode the hostname properly before using it in your project.
