Problem with SSH/TELNET connection to MSA 2040

Hi, I tried connect to HP MSA 2040 via SSH or TELNET interface. HTTP and HTTPs inteface running well and I have right settings of user permissions (manage role, CLI and SSH enabled). 

I tried connect from Win10 (CMD + TELNET), Win10 (PuTTY), Win2012 R2 (PuTTY and CMD + TELNET) and from Linux CentOS 7 (Command line with ssh command). Every time I receive this message:

"/home/appuser/appshell: line 34: mccli: Input/outpur error"

and connection is closed by remote host.

I think, that is something wrong or not set on storage HP MSA 2040. Could You help me, please, with advice?

Thank You
