what should i do?

[cmhuter]

I ran into the same issue today. The relevant line is:
[WARNING] switch_core_media.c:4155 NO candidate ACL defined, Defaulting to wan.auto

This means wan.auto is used as ACL for the ICE candidates which are as far as I can tell in your case just as in mine all private addresses. These are rejected by wan.auto which only accepts public addresses.

I fixed this error by adding an ACL to the profile where the WebRTC clients are registered ("lan" being the relevant list in acl.conf.xml):
<param name="apply-candidate-acl" value="lan"/>

See https://developer.signalwire.com/freeswitch/FreeSWITCH-Explained/Networking/3965687/#apply-candidate-acl
