Error Message :
Invalid credentials, reason: 'Global UC4 error' (1004)
U02000099 Transfer key could not be loaded (Ret='458752', minor='1004'). Please check, if the KeyStore exists and the agent is authenticated.
The Windows Agent loops at start up, if there is no transfer key, but the Agent is already “authenticated” within the Automation Engine.
Here an example which depicts the issue in detail and also the steps to reproduce:
Cause type: Defect
Root Cause: In the reconnect procedure of the Windows Agent. When the agent tries to connect or reconnect to the AE server and the authentication procedure fails (e.g., the transfer key is wrong, the key store file cannot be opened, or contains wrong information), the agent reconnects which ends up in a loop.
OS Version: N/A
Windows Agent 12.3 x
Renew the transfer key via the Administration Perspective in client 0.
