Links inside wordpress site are not opening after installing Cloudflare SSL

I have intalled ssl through Cloudflare for my domain aus.ac.in. I can access the url fine but all the other links under the dropdown from header wont open

Links: 1 ?2

Getting this error all over the places: (index):158 Mixed Content: The page at ‘https://www.aus.ac.in/’ was loaded over HTTPS, but requested an insecure script ‘https://www.aus.ac.in/wp-includes/js/twemoji.js?ver=6.2’. This request has been blocked; the content must be served over HTTPS.

This is my .htaccess:

I have tried to comment old rules and new ovveride rules in htaccess but it didnt work. It is hosted on-prem server. Also I cant access my wp-admin panel as well.
