I have see in your changelog "In v9601, SSH connections to remote systems failed if Password Manager Pro was running on an Ubuntu server. This has been fixed.". I have updated to v9700 and the problem is not solved!!!
I use Ubuntu 16.04.4 and with Version 9501 we had no problems with the SSH connections.
