[X2Go-Dev] x2go doesnt connect when using chacha ciphers

[bo0od]

When im trying to connect it says:

```
key error: no match for method encryption client -> server: server 
[chacha20-poly1305 at openssh.com], client [aes256-ctr, aes192-ctr , 
aes128-ctr , aes256-cbc , aes192-cbc , aes128-cbc, blowfish-cbc , 3des-cbc]
```

Though connecting using SSH works just fine. here is the sshd logs:


```

port xxxxx no matching cipher found. Their$

user root by user(uid=0)
```


first 2 attempts done through x2go which failed due to no matching 
ciphers , last attempt done through ssh which worked just fine.

If  you are asking what is my ssh and sshd configurations are you can 
find them here: (though its unrelated because ssh is working fine the 
issue is within x2go)
