A few of our clients have been having issues using a recent version of Rebex (2017R6, released october 25th). When they connect to some of their SSH machines, they receive one of the two following errors:
"Negotiation failed. Server signature is not valid."
"Negotiation failed. The connection was closed by the server."
Is this issue something we can work around in 2017R6 by changing a setting? If you need more information or an access we could ask our clients if they can provide it, since we haven't been able to reproduce the issue with our setup.
