Problem with Cloudflare vs NginxProxyManager SSL certificates

[aristosv]

I am trying to understand the logic behind SSL usage for NginxProxyManager.

• I have domain wviiv.com on Cloudflare
• SSL/TLS encryption for this domain on Cloudfalre is set to "Flexible"
• I have NginxProxyManager and a WordPress website running in docker

This is the configuration for this domain in NginxProxyManager

And this is the WordPress configuration

And yet when you visit the website, you'll see it's accessible via https. No errors or anything.

But when I try to create a new page in WordPress, I get the following error.

When I enable an SSL certificate in NginxProxyManager, the website stops working, with too many redirects.

I suspect these issues are related to problematic SSL/TLS configuration. Perhaps a conflict between Cloudflare and NginxProxyManager certificates?

So what is the correct way to use either a Cloudflare or an NginxProxyManager certificate?

First, it's not a good idea to use http instead of https between Cloudflare <-> your NPM instance. Does Cloudflare include the correct hostheader? When I try to access your website, I see the default page.
