[backlinkchatluong]

I always face 404 error when I access them

I dont know why and what’s happening
what did I go wrong?
Can someone help me to fix it?
my sites are backlink chat luong and kinh doanh online

Does this 404 show up on all URLs on the site, or is the main page okay? Based on just the image, it looks like you might have a configuration issue where the site is configured differently with SSL versus without. A lot of how to fix that will depend on how you manage the server.

Are you really using Let’s Encrypt? Both sites say that CN is “localhost” and the OU is “none”. And one of the websites, after passing the error, says
"Apache is functioning normally"

You should remove and recreate the certificates. Are you using certbot? If not, use it, supposing you have root access in that server
