zabbix behind nginx proxy manager, login works, but then 404 Not Found

[mx738]

Hello,

i install a fresh zabbix on a Proxmox LXC Debian 12 and nginx.
We have a NGINX proxy Manager for SSL Certificates

When i access the zabbix by IP everything is working well.
If i access by domain name, i see the Login screen, i'm able to login but then it shows:

https://my.domain.com/zabbix.php?action=dashboard.view

404 Not Found
nginx/1.22.1

On the nginx proxy i forward http IP-Address Port 8080

Any idea?

I got it behind an NPM as well without any issues. Dashboard URL is similar to yours so doesn't look like a Zabbix server issue.
In the NPM proxy host:
I got Scheme: http
Forward: my zabbix server ip.
Forward port: http port
Block common exploits, websockets support on
SSL tab: Force SSL, HTTP/2 support on

That should do the trick
