    Hello all,

    first and foremeost thank you for the amazing app you have provided on the clouron platform.

    I have just one annoying issue, and that is I can RDP to some of my machines, but others I cannot, the machines are on the same network so I am not sure what is going on. The machine that I cannot connect to just timeout.

    I have checked all the obvious things on the machines themselves but they are fine I can RDP them normally not using Guac so I am at a loss.

    The only thing pattern I can see is that the clouron is installed on my VMWare host, and the machines I can RDP on to are also on that host, where as the machines I cannot are physical machines, not virtual machines.

    I would not have thought that would be an issue but one of you amazing guru's maybe will know if it is.

    Any help will be gratefully received.

    Many thanks in advance

    Scott

      @scott-edwards81 are you connecting to the hosts my host name or IP address? It could be that the DNS resolution is not workin via Cloudron.

        @girish hi many thanks for your reply, I am connecting via IP, so not to involve DNS in the equation, because I thought that might cause an issue.

          I have ommited the IP address and username from the snippet for security. but hopefully this should give you some clue perhaps as to what might be happening.

          Kind Regards

            @scott-edwards81 said in Cannot connect to all servers on same network using RDP:

            Nov 23 10:50:07 guacd[294]: DEBUG: freerdp_tcp_connect:freerdp_set_last_error_ex ERRCONNECT_CONNECT_FAILED [0x00020006]

            I would try two things:

            • Are you able to also telnet <ip address of machine> 3389 using the Web terminal of the app?
            • If the above works, are you able telnet <ip address of machine> 3389 from the VM?

              @girish many thanks for the advice I did as you asked and I could not telnet to the server via the terminal app, so I then went to the cloudron server and tried it from there it would also not work, which lead me down a bit of rabbit hole 😄

              Eventually I managed to find and issue with the virtual nic on the server itself and managed to resolve that, and now it is working perfectly.

              Not sure how I missed it but you helped me find so many thanks.

              Kind Regards

              Scott
