How to activate the blue url for wordpress

My host has installed comodo on the server and activated it for my domain.

I am the admin of the website.
How do I activate the blue url for my wordpress-website permanently?
Tried different plugins. The best I got out was a blue url for 2 seconds and only sometimes a https url.
Is there any wordpress-plugin or manual for the latest wordpress version?

Apologies, I’m not really sure what any of that means. As a guess, it sounds like you’re trying to access a site running wordpress and you’re being blocked?
