Workaround would be to:

a) Skip the $self address in either of gmcast.listen_addr (this skipping that option) or removing $self from wsrep_cluster_address.


As mentioned in description following in gmcast.cpp seems to be causing it:
====================================================

    if (initial_addrs_.find(listen_addr_) != initial_addrs_.end())
    {
        gu_throw_error(EINVAL) << "connect address points to listen address '"
                               << listen_addr_
                               << "', check that cluster address '"
                               << uri.get_host() << ":" << port
                               << "' is correct";
    }
