Compatibility of ZeroMQ sockets written on different languages

I've built an app written on python, based on ZeroMQ, but now I'm facing perfomance issues. So I decided to rewrite some modules of my app using, let's say, Golang. But when I try to establish messaging between sockets, implemented by different languages, anything does not work.

I've searched so far, but I didn't find any info about compatibility problems of ZeroMQ using different languages.

So the question is: Can I use golang for server implementation based on ZeroMQ and client written on python to connect to it?
Or do I have to use only one language?

EDIT: here are typical server and client that I'm trying to get working properly

server:

import zmqctx = zmq.Context()
sock = ctx.socket(zmq.REP)
sock.bind("tcp://*:57000")
msg = sock.recv()

client:

package main

import (
    zmq "github.com/pebbe/zmq4"
)

func main() {

    ctx, _ := zmq.NewContext()
    sock, _ := ctx.NewSocket(zmq.REQ)

    sock.Connect("tcp://localhost:57000")
    sock.Send("simple message", 0)
}

Server stucks at sock.recv()
