I have a laravel app that sending email to my customers. I send email through Hotmail. It works fine on localhost but when I upload it to serve it is showing above error. All Credentials are correct. NOTE: My main domain is Cloudflare. Is there any configuration for sending email from laravel if a domain is on Cloudflare
