Failed to close session EOF

[Shadasviar]

I have Weles and Boruta configured on debian machine (running on this Vagrant machine). I can create Boruta requests, execute commands on DUT etc. When I run Weles job with this yaml
(link for test is valid), job fails immediately without starting even dut_boot.sh script.

In journalctl I see error:

Feb 23 20:42:53 ubuntu-bionic weles[25724]: 2019/02/23 20:42:53 Failed to close session EOF

Test I try to execute is here.
Dryad I use is configured in this Vagrant file and works with Boruta greatly.
Weles and Boruta are running on the same machine and Boruta use default ports.

In my case error was caused by missing sshfs on supervisor. Installing sshfs resolved problem.
