I think this is related to #3177 which was fixed recently, but the subclass is different.

We can't reproduce errors unless there's a specific set of steps to reproduce the issue, including the project itself.

If you can provide concrete steps to reproduce the problem, please add them and reopen this issue.

I encounter this bug in my project too. The root cause seems to be that the change in #3177 is not backward-compatible with older version. If I'm using a net-ssh smaller than 6.0 (5.2 in my case) then I will encounter this bug.

Also running into this.

Using a net-ssh version below 6 seems to be the issue like pointed out above, as it does not happen if I use a version >= 6
