CodeIgniter 3 routes don't work in HTTPS

When you say "not working", what exactly do you mean?

Is your site returning any error?

---

More so, your rewrite rule has a ? which is different from what is seen in the docs here. Is that on purpose?

See the difference. Your code:

Code:

RewriteRule ^(.*)$ index.php?/$1 [L]

CI Documentation:

Code:

RewriteRule ^(.*)$ index.php/$1 [L]
