Yes, that’s what I do:
Computer A => SSH => Computer B karaf console: did work before and work now
Computer A => PuTTY SSH => Computer B karaf console: did work before but since then update no connection can be established
Thank you Bruce.
Usually the network connection is established before the access data is requested.
But in my case is no TCP connection established at all.
I run into the same problem. There is a log message regarding cipher. This means you need a newer version of putty because older versions do not support the needed cipher to access ssh.
