[Neustradamus]

Try with 1.3.2 ^^

[Neustradamus]

@s-nt-s: Any news?

Have you tested with "master"?

• https://github.com/fritzy/SleekXMPP/commits/develop

It works?

[s-nt-s]

Yes, I have tested with master, and It doesn't work.
Is sleekxmpp unmaintained? Should I migrate to another library?

[s-nt-s]

new logs:

My environment

$ python3 --version
Python 3.6.9
$ python3 -c "import sleekxmpp; print('sleekxmpp=='+sleekxmpp.__version__)"
sleekxmpp==1.3.3
$ wget https://raw.githubusercontent.com/fritzy/SleekXMPP/develop/examples/echo_client.py
