Client don't start

I have a problem. My client don’t start automatically on Linux mint 18.3 Cinnamon 64B.
What shall i do?
best Regards,

Isn’t there a checkbox for autostart?

Yes it is. It’s on.

Well, i have installed this version of the client: and it is working on my Mint 18 workstation.

I have installed your client version… And this morning, the client don’t start automatically.
