The Single Connect License Manager enables the software’s licensing model based on module, device count, user count based on proxy, admin count, concurrent SSH/Telnet sessions, concurrent RDP, total concurrent sessions (RDP+ SSH/Telnet), and session time. Only authorized users can manage the License Manager.
To upload a new license file:

1. Log in to the Single Connect Web GUI.
2. Navigate to **License Manager**.
3. Click **Add New License File **and select the license file.
4. Establish an SSH connection to Single Connect from port 22 and restart the Web Portal service using the command **systemctl restart pam-gui.**

Then restart other proxy services using the commands, **systemctl restart pam-ssh**, **systemctl restart pam-sql**, **systemctl restart pam-http**, and **systemctl restart pam-sftp**.
