Original GitHub issue: https://github.com/amnezia-vpn/amnezia-client/issues/379

Amnezia android client try to connect to ssh when connecting with shared connection (not server):

Oct 17 14:41:04 ftn sshd[2219949]: Invalid user  from x.x.x.x port 39894
Oct 17 14:41:04 ftn sshd[2219949]: Failed none for invalid user  from x.x.x.x port 39894 ssh2

If my wife and children connect to vpn in several minutes interval - fail2ban ban all connections to vds, because too many ssh errors from ip.

To Reproduce
Steps to reproduce the behavior:

create server (in my case - cloak+openvpn)
share connection (not server) to another client
connect with shared connection
see ssh logs

Expected behavior
No ssh interaction at all with shared connection.

Looks like you had shared full access to your family, usually you don't need to share full access, just share vpn configs.
By the way, AmneziaVPN 4.0.8 beta is released, you can try it - https://github.com/amnezia-vpn/amnezia-client/releases/tag/4.0.8

It was not "Share server", it was "Share for Amnezia". In decoded url i does not see user/password.

In 4.0.8 only first connect try to login with empty user.
In Debian terminology — minor bug.
