firewall alias (IP of host) does not work in caddy handler, IP address does

[gerk59]

In firewall alias a host alias is defined:  server -> 192.168.x.y
Using this alias as upstream domain in a caddy reverse proxy, doesn't work (resulting in error 502, bad gateway)
Using the IP address of server does work.

In 25.1 the alias did work.

Are you maybe confusing a firewall alias with an unbound host override?

I used the same name for both. Will check again, thanks.
