''User/terminal is over the <color red>maximum Total number of terminal licenses</color> concurrent connections: user=<color green>EmployeeNo.</color> terminal= <color purple>ClientAddress/ClientDeviceID</color> company= <color orange>Company</color>''

The current status of the license usage can be seen on a webpage of the Service Broker:
<code>http://<IP>:<PORT>/api/admin_accesstokens</code>
where the IP is the IP address and the PORT is the port number.

====3.3. SCAN subscription license issue====

**Issue**\\
''**Error: **
User/terminal is over the maximum 1 concurrent connection''

**Solution**\\
Customers with subscritpion licenses must restart //Service Broker// at least once every 28 days to refresh the license to avoid this connection error. When the //Service Broker// restarts it always checks the portal for a new license.

<WRAP round box> **Note:** It is recommended to schedule a task in **Windows Task Sceduler** to run a weekly restart for **Service Broker**.</WRAP>
