When im trying to connect it says:
key error: no match for method encryption client -> server: server

aes128-ctr , aes256-cbc , aes192-cbc , aes128-cbc, blowfish-cbc , 3des-cbc]
Though connecting using SSH works just fine. here is the sshd logs:

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)

Though connecting using SSH works just fine. here is the sshd logs:
X2go is not using openssh bit libssh which may or may not cover the required ciphers. You might need to use an updated libssh and I think this requires recompiling x2goclient.

I see, Hope you guys put it into consideration asap.

i have talked to libssh dev on IRC channel they said libssh supports chacha and i have installed x2goclinet v4.1.2.2 with libssh 0.9.4-1 (both from sid debian repository)
They said x2go might be restricting its ciphers or not using libssh configs.

I don't think that x2goclient is restricting something here. Unfortunately I do not know more about x2goclient's use of libssh so I cannot help further.
@Ionic: Can you help?
