UI reachable using IP but not domain

I have 2 RoPieee endpoints (let’s call them A and B) which should be configured exactly the same way. I can stream through them just fine, but I am seeing a minor issue:

A’s UI is reachable both using the hostname (http://A.local) and the IP, but B is only reachable using the IP. Also, on A’s ‘Devices’ page, B does not show up. When I ‘ping B.local’ on the command line the hostname resolves to it’s IP just fine. Any idea what’s going on?

Cheers,
Ingo

.local makes use of MDNS (Multicast DNS). There are a number of things that can go wrong. One of them is that your router plays an important role here.

It can resolve itself after a while, resetting your router and the Pi’s might to the trick as well.

oh. one more thing: would be great if you can send me feedback from the B unit (without rebooting it!)

Thank you! Feedback sent (690882f080658e33)

Tried rebooting router and PIs but problem persists

Hmmm… this one looks good. Can you send me feedback from the other one?
