Troubleshooting


Problem

When testing a TM1 datasource connection created on Cognos BI, the following errors will be displayed and test will fail: TM1-ERR-0052 An attempt to login to the TM1 server failed. The TM1 error code is 84. The TM1 error message is "SystemServerConnectionFailed" XQE-EXE-0004 QFWBridge has returned an error: TM1-ERR-0059 The server is not responding Additionally, when testing the datasource, considerable delay in time to response is observed

Symptom

Other TM1 data sources may be already configured and working correctly.

They may be successfully tested but a new connection to the same TM1 machine will fail

When pinging the TM1 server in order to assure connectivity, a "time out " may occur although other TM1 data sources can be reached and tested correctly.
