Re-establishing an On-Premise to Cloud Connection with the STP OnPremise Connector

When to Use This Workaround

Note: This is only relevant for installations with an OnPremise Connector version lower than 1.8.0.

You should use this workaround if you see the following error message in your STP OnPremise Connector logs:

user connection limit (8) is reached

The STP OnPremise Connector log file is usually located here:
“C:\Users\Public\Desktop\STP AG\STP.OnPremise.Connector\Logs\LogFile.txt”

Steps to Reconnect

1. Connect to the local server where the STP OnPremise Connector (OPC) is installed.

2. Open “Services” and look for the service called “STP OnPremise Connector”.

3. Stop the “STP OnPremise Connector” service (for example, by right-clicking and selecting Stop).

4. After stopping the service, wait at least 5 minutes before proceeding. This is necessary in the scenario described above because the connection to the cloud goes through several stages. The involved components may need some time to properly detect and clear the closed connections before the STP OnPremise Connector can reconnect.

5. Start the “STP OnPremise Connector” service again (for example, by right-clicking and selecting Start).

6. Open the STP OnPremise Connector log file to check the connection status.
   You can find the log file at: C:\Users\Public\Desktop\STP AG\Logs\STP.OnPremise.Connector\Logs\LogFile.txt

7. Look for the following entries in the log:

   • “INFO Queue OPC.Your-Tenant-Guid_Persistent on opconnector.stp-cloud.de:5673 successfully created”
   • “INFO Queue OPC.Your-Tenant-Guid_Transient on opconnector.stp-cloud.de:5673 successfully created”

   Note: Your-Tenant-Guid is the GUID of your tenant. You don't need to look this up or verify it—this is just for explanation purposes.

   

   If you see these entries, your system has successfully reconnected to the STP Cloud.

8. For a final check, you can log in to your connected tenant (https://your-tenant.stp-cloud.de) and go to All Applications –> Tenant Admin –> On-Premises to view the connection statistics. (Direct link: https://your-tenant.stp-cloud.de/tenantadmin/#/onpremises) >Warning: If you see the following, your OnPremise Connector is still not connected. Please do not click “Connect”, as this will change your connection data for the OnPremise Connector.

   If you see the following screen instead, your OnPremise Connector is properly connected again.
   

If you have trouble reconnecting, please contact STP Support.
