Hi Kevin, Thank you for very much for checking and providing some information regarding this matter. From further checking, it seems the SRV PROBING test failure we encountered is related to some misconfiguration or issue in Avahi. We were able to pass this test once we applied the following updates: Remove the "%h" wildcard from the DNS-SD name Advertise only one DNS-SD service For now, we think it is better to consult the Avahi project in order to understand the above limitation. Thank you.
