Keyboard interactive SSH login fails

Hello,

I am evaluating the use of remote.it for our LoraWan gateways, which are based on openWRT.
I managed to get to the webinterface through the web protocol, but I’d like to also have SSH acces to reduce data usage for 4G devices.

The problem seems to be that the device uses keyboard-interactive authentication. When I use Putty to connect, I get an error saying that the server unexpectedly closed the connection. When using powershell, I get:

kex_exchange_identification: Connection closed by remote host

When not using remoteit, I can open the ssh connection with Putty, where I get a prompt to fill in user and password.

Please see:

Does this solve your problem?
