The problem was caused by the usage of request.getServerPort() to match local port config, which was failing if the request was being forwarded and port was being switched, for example in our case Tigase http-api was configured to listen on port 8080 (default) but on the outside we were listening on port 80 (port forwarding in docker), and because there wasn't any configuration for port 80 in Tigase then no redirection has been made.

Using request.getLocalPort() solves the problem.
