mDNS lookup fails #12210

Open carmiac opened 4 years ago

carmiac commented 4 years ago

I have envoy setup between two machines servers on my local wifi network. The server side is using Avahi for mDNS and all of the normal tools (ping, ssh,etc) on my client machine can find it just fine. Envoy, however, can't find it using a hostname, but has no problems with the direct ip. Also, having my hello client directly talk to the server-side envoy without going through the client side envoy works fine. Here's my server and client side config, plus the log from the client-side envoy.

Client config:
