I have created a website called cravestore.in in magento2.4. I have registered myself by using Signup page, all works good, but when I tried to login with my correct credentials the customer login page just refreshes instead of completing the login process. Also, when I tried to reset the password the forgot password email is not coming on my registered mail id. Please fix these issues.
It seems like referrer key is not working correctly in your Magento instance. This is a feature provided by Magento. It is used to redirect a user back to the page where he tried to login to resume his navigation. For example, if a user is on a category page and clicks on login link, it will add category page as referrer in URL and will redirect the user back to the same category page after successful login. I can successfully logged in to your Magento instance without the referrer key.
While you are still debugging it and you want to make the login form work in the same time, you can disabe the referrer key feature in configuration in admin panel.

Redirect Customer to Account Dashboard after Logging in to
Yes and you will not see referrer in the URL anymore. But this will always redirect a user to customer dashboard after login.
