Why does the TV not see the DLNA server?

Question

DLNA

Actually, if you turn off firewalld, then everything works.
If you turn it on, the TV does not see the dlna server.
Port open:

sudo firewall-cmd --list-all
public (active)
  target: default
  icmp-block-inversion: no
  interfaces: eth0
  sources: 
  services: dhcpv6-client
  ports: 8895/tcp
  protocols: 
  masquerade: no
  forward-ports: 
  source-ports: 
  icmp-blocks: 
  rich rules:

Here is the connection with firewalld disabled:

java     2153 serviio  176u  IPv4 209942      0t0  TCP 192.168.1.46:8895->192.168.1.64:42384 (ESTABLISHED)

What else needs to be configured?

Answer 1

I saw ssdp:
Opened ports. Now it's set up like this:

sudo firewall-cmd --list-all
public (active)
  target: default
  icmp-block-inversion: no
  interfaces: eth0
  sources: 
  services: dhcpv6-client
  ports: 8895/tcp 1900/udp
  protocols: 
  masquerade: no
  forward-ports: 
  source-ports: 
  icmp-blocks: 
  rich rules:

Now works with firewalld enabled.

Answer 2

it means that the wrong port is open or not only that
