Thank you for the report.

First of all please check whether the device supports SSH2. SSH1 is insecure and due to this obsolete. It's hard to find SSH1 server these days.

I think that the combination (or introduction) of certain changes for SSH2 could break compatibility between the component and the SSH1 server. Another possible reason is the large number of changes we've made in SecureBlackbox 12 which could introduce an issue. We will check SSH1 implementation in our conditions. But please do check the possibility to use SSH2 instead.

Sincerely yours
Eugene Mayevski
