Hi, Alen! I've tested your blog domain. This is a really interesting situation. Your main domain & www subdomain seems like pointing to Hashnode normally. However, the certificate that has been given by Hashnode is valid only for www.devopsengage.com Hard to say where you've made a mistake (or it is something from Hashnode side) I can recommend you to create a special subdomain for Hashnode blog, like blog.devopsengage.com And create a redirect from your main website devopsengage.com to blog.devopsengage.com (while you don't have any other content) For example I am redirecting my domain *.theceman.dev to my Github page, and blog.therceman.dev is connected to hashnode
