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.
