Prosody server with onion domain

[Валентин Федосеев]

Hello, I set up the XMPP Prosody server in conjunction with the onion domain, it works fine with v2 domains, but when I trying to configure it with onion v3, it does not connect. Everything is clear in prosody logs, there are no errors, but the jabber client simply does not connect. 

For onion v2, I used this

sudo apt install tor prosody 

printf "HiddenServiceDir /var/lib/tor/jabber\nHiddenServicePort 5222 127.0.0.1:5222\nHiddenServicePort 5322 127.0.0.1:5322\nHiddenServicePort 5269 127.0.0.1:5269\n" | sudo tee /etc/tor/torrc sudo service tor restart 

sudo nano /etc/prosody/prosody.cfg.lua //here i just add admin and virtualHost with my onion domain

sudo openssl req -new -x509 -days 365 -nodes -out "/etc/prosody/certs/host.crt" -newkey rsa:2048 -keyout "/etc/prosody/certs/host.key" 

sudo service prosody restart

after that just adding users and it works fine. On client (pidgin) i set SOCKS5, port 9050 OS ubuntu 16.04, I also tried it on 18 and 20, the result is the same. 

What could be the problem and in what direction should you look for a solution?
