Hello all,

I compiled and installed Janus 0.13.4 on an Amazon EC2 server (Ubuntu 22).

When I try to test “VideoRoom demo” audio and video streams are published and received by participants, but i always get the following warning message on the server:

[WARN] [6637365782759827] Failed to add some remote candidates (added 0, expected 1)

I configured the server as follows:

…
nat: {
nice_debug = false
ice_lite = false
nat_1_1_mapping = {PUBLIC IP}
keep_private_host = false
ice_ignore_list = “vmnet”
}
…

What could be causing the warning message?

Thanks in advance,

Try disabling mdns if you don’t need it.

Thanks for the reply Lorenzo, I tried disabling the mdsn parameter but it always shows me the same warning message.
On the 0.10.x version that I had previously installed it was not shown.
What does that warning message mean? could it depend on the version of some library?
