SSL CERTIFICATE- ISSUE

Hi everyone.

I am a new member to this forum.

I just want to ask that I never tried to install any SSL on my travel website ghumakkadd.com.
When I checked that if my website is having an SSL or not, it showed me that I have a SSL on my website by COMODO.
I spoke to helpline on COMODO and they said to check it from my hosting provider.
Now after I have spoken with my hosting provider, they said that they can help me install new SSL as there is webhost server mismatch.

My question is if my website is already having SSL how can i configure it so that my domain is redirected from http to https.

Kindly help.

Thank you so much in advance.
