Init7 IPTV stopped working after updating to UDM SE v3.1.15

[sulzer]

After updating to the latest Unifi firmware 3.1.15 on my UDM SE, I've re-installed udm-iptv as I always do after a firmware upgrade. Everything seems to be properly configured as it was before, however since UDM SE 3.1.15 I can't get any IPTV stream anymore. I've double checked that the firewall rules to allow IGMP traffic are there and disabled the Windows firewall as well (I'm testing with VLC media player).

This is my config:

## Example configuration for udmp-iptv ##
# Interface on which IPTV traffic enters the router
IPTV_WAN_INTERFACE="eth9"
# ID of VLAN which carries IPTV traffic (use 0 if no VLAN is used)
IPTV_WAN_VLAN="0"
# Name of the IPTV VLAN interface
IPTV_WAN_VLAN_INTERFACE="iptv"
# IP ranges from which the IPTV traffic originates (separated by spaces)
IPTV_WAN_RANGES="224.0.0.0/8  239.0.0.0/8  77.109.128.0/19"
# DHCP options to send when requesting an IP address
IPTV_WAN_DHCP_OPTIONS="-O staticroutes -V IPTV_RG"
# LAN interfaces on which IPTV should be made available
IPTV_LAN_INTERFACES="br1200"
# Disable quickleave for igmpproxy
IPTV_IGMPPROXY_DISABLE_QUICKLEAVE="true"
# Enable debugging for igmpproxy
IPTV_IGMPPROXY_DEBUG="true"
IPTV_WAN_DHCP="false"

IPTV_IGMPPROXY_PROGRAM="igmpproxy"

IPTV_IGMPPROXY_IGMP_VERSION="2"

This is the output of udm-iptv diagnose with debugging enabled:

Before 3.1.15 IPTV was running smoothly. Any ideas? Thank you in advance!

This might be related to this issue:

You shouldn’t be starting/looking at the igmpproxy service, instead you should use udm-iptv.service.

Hi @fabianishere

Thank you for your reply, much appreciated.

I'm not sure what the issue last time was but I've done another re-install of udm-iptv and now it works perfectly like before.

Thanks once again!
