SSH Connection error to an AIR-CT3504-K9

[stefanoroma]

Hi, I'm trying to develop an ssh client with Chilkat ssh library for c# but I get the following error:

SendReqShell:
    DllDate: Nov 17 2022
    ChilkatVersion: 9.5.0.93
    UnlockPrefix: Auto unlock for 30-day trial
    Architecture: Little Endian; 64-bit
    Language: .NET 4.7 / x64
    VerboseLogging: 0
    channel: 101
    Sent shell request
    Unexpected message type received in response to shell request.
    messageType: 94
    Failed.
  --SendReqShell

The WLC that is having this issue is running the firmware version: 8.10.130.0

I don't have this issue with another CT3504-K9 WLC which is running a different firmware: 8.5.161.0

The login is made thru username/password and that doesn't seems to be the issue because from show logging I get "user login success"

 - For starters , check if the current controller can accept 'regular ssh connections' , such as for instance from PuTTy ,

Hi, yes it can.. I don't know why but if I try to create a second shell right after the first one the shell does open.

you need to capture more information each stage of your program and get output what is process to know why that is generating another ssh session ?

this is more of Library and program you using.
