Can't use my own SSL certificate for Portainer?

I set up the [Nginx proxy manager
container](https://nginxproxymanager.com/) to avoid the "not secure"
warnings on my internal Docker containers. They all seem to work with
my duck.dns SSL certificates and I can access them using custom domain
names (e.g. [Plex.duck.dns.org](https://Plex.duck.dns.org)) but when I
try it with Portainer, I get this error on Chrome. Firefox and other
browsers don't show the error but tell me that my connection is still
not secure. Does anyone here know why and how I could fix it?

Check the Nginx proxy host config that destination/forward
hostname(ip) is the local IP and forward port is correct.  E.g.
192.168.x.x 9443

This is unlikely to be a portainer issue and more a config issue with
that server in npm. Bit hard for us to troubleshoot without seeing the
real error behind this. What does a browser like edge tell you? What
does this one say say if you click details?
