New Install - reach local-ip/admin but not working

[wisdomlight]

Expected Behaviour:

What I think should be happening:
by accessing local-ip-add-of-device-on-which-PH-is-installed/admin I should see the Admin Web Interface
I should be able to connect my iPhone to the PH server

In the home router I made the PH server address a statitc one

Server details:

Debian 12
MacBook Air (hosting Plex with port 32400 forwarded to router's port 32400)

Client details:

EndevourOS
in Network Manager I changed the IPv4 settings to
Automatic (DHCP) addresses only
In the DNS servers filed I added the ip-address of the server
in the additional static addresses I added the PH servere static address
iOS
Latest OS

Actual Behaviour:

Connecting to PH server via Firefox browser returns only the html, not the css

This may be helpful?

sherab@debian:~$ systemctl list-units --type=service | grep failed
● lighttpd.service                                      loaded failed failed  Lighttpd Daemon
● networking.service                                    loaded failed failed  Raise network interfaces
● pihole-FTL.service                                    loaded failed failed  Pi-hole FTL

Here's another debug token after pihole -r (repair) was run

Your debug log shows a number of problems.

dnsmasq is running on port 53, which prevents pihole-FTL from binding to that port:

[✗] udp:10.0.3.1:53 is in use by dnsmasq (https://docs.pi-hole.net/main/prerequisites/#ports)

Stop and disable dnsmasq, then restart pihole-FTL with pihole restartdns.

Apache is running on port 80, and this is preventing our shipped webserver (lighttpd) from binding to that port:

[✗] tcp:*:80 is in use by apache2 (https://docs.pi-hole.net/main/prerequisites/#ports)

You have a few options. Stop and remove Apache2, move Apache to a different port, or move lighttpd to a different port.

Thank you @jfb
It works now.
two things

1. Do I need to set my iPhone DNS to manual and enter the ip address of the machine that hosts the PH? or is it enough to select the iPhone from the PH web admin panel where it says clients
2. I want to say big big THANK YOU for the truly professional service you are giving. Even though I haven't used PH for few fears now, nevertheless I remained a Patreon supporter because you guys are simply fantastic.

You should not have to manually assign the DNS on your phone. Typically your DHCP server (either router or Pi-hole, depending on how you have set this up) will provide the DNS server in the DHCP handshake.
