    Hi Slava,<br>
    <br>
    I see you use 3.0, so I pushed a small commit to print more
    information - this will help to understand your failure.<br>
    <br>
    Update and be sure you have this commit <br>

            Maybe the same destination may be reached (from the IP
            routing table perspective) via multiple interfaces like via
            interface A and interface B - and OS (via mhomed) selected
            interface A , but OpenSIPS listen only on B.<br>
            <br>
            Such a setup may lead to the error you listed - OS picking
            up for routing a local interface that is not used by
            OpenSIPS.<br>
