Description

Since I had my remote two I used several external integration. With firmware 1.8 only 1 of 5 is discovered. avahi-browse --all in my network shows:

• enp7s0 IPv6 remotetwo-integration-harmony _uc-integration._tcp local
• enp7s0 IPv4 uc_denon_driver _uc-integration._tcp local
• enp7s0 IPv4 ucr2_dunehd_driver _uc-integration._tcp local
• enp7s0 IPv4 requests _uc-integration._tcp local
• enp7s0 IPv4 uc_androidtv_driver _uc-integration._tcp local
• enp7s0 IPv4 remotetwo-integration-harmony _uc-integration._tcp local

The only one found is remotetwo-integration-harmony. The difference to the others is that it is the only one which also reacts on IPV6. Is it possible that IPV4 is ignored if IPV6 is used at least once?

I updated the source of AndroidTV, DuneHD and Denon on friday to be on the most recent version. I used my setup before with the same directory structure. I use ports 8000..80006 but also tested other ports.

If one of the missing integrations is included in an former update it is not discovered but is still active and is working. In my case I still can use requests (HTTP-Post) even though is is not discovered anymore.

How to Reproduce

1. create a few external integration with at least 1 using IPV6
2. try to discover all external integrations.

Expected behavior

Normally all integrations should be shown but I think only the IPV6 integration is shown.

System version

1.8

What part of the system affected by the problem?

No response

Additional context

I am not 100% sure about IPV6 anymore. I stopped the IPV6 integrations, cleared my local avahi cache and the other integrations are still not found. I restarted remote 2 to be sure that the cache is also cleared there but still no external integration is discovered.

Any idea concerning external integrations?
