Maybe define a new API in connections_manager:

      template <typename F>
      void for_connection(uint32_t connection_id, F&& f) {
         any_of_connections([connection_id, f = std::forward<F>(f)](const connection_ptr& c) {
            if (c->connection_id == connection_id) {
               f();
               return true;
            }
            return false;
         });

if (c->connection_id == connection_id) {
c->close( false );
return true;
}
return false;
});
