"Error (Error Code 2): Protocol error occurred.

I have compiled softether from git clone on two servers. One running Ubuntu 16.4.1 and the outer running xubuntu 16.10.
There are differences in the libs versions. Readline 6 vs 7 for example.
Now, when cascading hubs between the two servers I get this problem:
"Error (Error Code 2): Protocol error occurred. Error was returned from the destination server."
Any ide what could be wrong? Can it be the differences in compile machines?

I just upgraded so I have two 16.10 mashines. Then recompiled SE.
I´m still getting error 2?

I have disabled the fire wall on both sides. No luck. This configuration worked before upgrade.
Anyone having similar issues?

Solved it!
Do not use TLS 1.0 can not be checked!
But I do not want to use TLS 1.0. How can I get this function to work?

I'm not really sure whether 16.10 is really tested at all.
Are you getting this problem with 16.04?
What do you mean can not be checked? is it dimmed or nothing happen when you click it?

You can click it. "Do not use TLS 1.0" is marked. But hub cascaded to hub do not connect.

"Do not use TLS 1.0" is an option for using SSL 3.0.
Do you want it really?

No not really... thought it was for TLS 1.2
Sorry about the confusion.

There is following function in latest version.
>Added the function to allow to configure specific TLS versions to accept / deny. In the VPN Server configuration file you can set Tls_Disable1_0, Tls_Disable1_1 and Tls_Disable1_2 flags to true to disable these TLS versions individually.

Thank you!
And I can perhaps disable SSL 3 the same way?
