Cloak

I have a problem on Ubuntu 18.04 LTS. I setup a server with Shadowsocks & Cloak using HirbodBehnam's script. Everything works fine with Windows & Android clients. But, unfortunately, I could not use the client in Ubuntu 18.04 as Hirbod described in here. I double and triple checked the entire workflow. Everything seems good but, I do not have access to internet through the client. I also described the issue here. The log of our listening server on the client is as below:

My ckclient.json file is like-this:

{
	"Transport": "direct",
	"ProxyMethod": "shadowsocks",
        "EncryptionMethod":"plain",
        "UID":"MY-UID",
        "PublicKey":"MY-PUBLIC-KEY",
        "ServerName":"www.bing.com",
        "NumConn":4,
        "BrowserSig":"chrome",
        "StreamTimeout": 300
}

I checked the shadowsocks server on my client. It seems that is in a proper status:

sn@sn-pc:~$ systemctl status shadowsocks-libev

Hi, what does the log say for ck-server? Can you see the new session? Does it provide a reason for closing the sessions?

@cbeuw Sorry for late. The server log is as below:

ck-server[32707]: time="2020-01-18T05:42:56-08:00" level=info msg="Session closed" UID="znIN89zggdGKtJPNt7R9F1Q==" reason="Received a closing notification frame" sessionID=1932201206
