Hello, we are working to design a FPGA's farm using an Intel NUC as the remote machine where we will connect the clients (on their respective machines) for the control and monitoring of the farm. We are using the DSEII of the Quartus Prime Lite II program, version 21.1. We were already able to make the connection between the machines, but we get an error when performing the Exploration. We get the following error:
Starting Design Space Explorer

As you can see, after connecting, it takes a while for the error to appear and then nothing else happens. So we wonder what could be causing this error. We use the following settings:
Hostnames: 192.168.69.72 (IP adress of the Intel Nuc)
Job per host: 1
Custom SSH port: 22
private_key: D:\Documentos_Escuela\Servicio\Puty\id_rsa.ppk
Quartus Root Path: /opt/intelFPGA/21.1/quartus
SSH Client: C:\Program Files\PuTTY\plink.exe
Farm Operating System: linux
Local to Remote Path Mapping: D:\Documentos_Escuela\Servicio\Codigos;/home/lab/Codes/FPGA
Initial Working Directory: /home/lab/Codes/FPGA

Hi,
Do you able to resolve the issue by disabling the firewall?

We suspect the issue is that the local host is not accepting connections from the remote host.
Could you please check your firewall settings to see if it might block the connection? If needed, you may consult with your IT for assistance.
In your project directory there should a dse_ssh_job_*.log file, does that report any problems?
In the project path, you should see shell scripts that DSE has created quartus_worker_*.sh, can you try running them manually and see if there are any errors?
Best Regards,
Richard Tan

We reviewed dse_ssh_job_*.log files and found these errors:
"dse_ssh_job_dse1_1":
FATAL ERROR: Network error: Connection timed out
"dse_ssh_job_dse1_2":
FATAL ERROR: Network error: Software caused connection abort
"dse_ssh_job_dse1_base":
Connected Successfully
Setting up environment variables
Changing to initial working directory
Ready to launch quartus_worker
Also, we ran the scripts manually in the remote machine and we got multiple errors which we attached to this reply. We don't think it's a firewall issue because we can connect via SSH using PuTTY and other applications without any problems. We would appreciate your prompt response to this problem.

Could you please try disabling the firewall to confirm if that's not causing the issue? Some customers have faced similar problems due to firewall configurations.

Yes, the error was due to a third party firewall (McAfee). Thank you for your support.
