DLNA/IGMP snooping issue

RouterOS Beginner Basics

Hi
I installed Jellyfin on my server and I’d like to share its contents to my smartTV. Jellyfin uses DLNA for device discovering.
Here is my setup

By reading this on the Mikrotik wiki here:

https://help.mikrotik.com/docs/pages/viewpage.action?pageId=59277403#BridgeIGMP/MLDsnooping-BasicIGMPsnoopingconfiguration

I only added the igmp snooping setup to it :

/interface bridge
add igmp-snooping=yes multicast-querier=yes name=bridge1 vlan-filtering=yes

and got this:

/interface bridge mdb print

Flags: D - DYNAMIC
Columns: GROUP, VID, ON-PORTS, BRIDGE
#   GROUP              VID  ON-PORTS         BRIDGE 
0 D 239.255.255.250     10  ether2-access10  bridge1
1 D 239.0.0.250         20  ether4-access20  bridge1
2 D 239.255.255.250     20  ether4-access20  bridge1
3 D 239.255.255.246     30  ether5-access30  bridge1
4 D 239.255.255.250     30  ether5-access30  bridge1
5 D ff02::1:ff92:2c24   30  ether5-access30  bridge1

However, my smartTV still can’t see media contents on the server.
For the record the Plex app works perfectly, so I don’t think there is any network issue, apart from the IGMP thing.
Could you help me figure it out please?

Thanks
