Below is the configuration I currently have. It’s important to note that the activity works correctly on my computer, and I can also establish the connection manually on the machine using PuTTY without any issues.
If it works locally and via PuTTY, the issue is with the robot environment.
Check network/firewall access on the target machine, make sure the robot is running in user mode (not service), and try changing terminal type (VT220 → VT100).
It’s usually a machine or permission issue, not the Terminal Session config.
