Sorry, I don't have a VCL for Wordpress Varnish configuration which I use.

Please see Configuring Varnish for WordPress for the VCL. It might work for you. Make sure to change "backend default" and the "acl purge" as I have described in my post.

I'm not sure about the "The plain HTTP request was sent to HTTPS port" error. Have you change the NGINX configuration etc?

I have configured it but when i turn on varnish images dont load on the site and if i want to access via url then it redirects to main site
