Error while trying to connect from desktop client version 12.4 (build 1324) to CA WA (Workload Automation DE) server 12.4 (cum#3). The same connection from desktop client 12.3 (build 3778) to WA (Workload Automation DE) server 12.4 (cum#3) is working fine.
CA Workload Automation DE Desktop Client and Server with 12.4 cum#3 patch
Time sync between Desktop Client and Server was more than 1 minute.
Once the time was sychnronized on the operating system (by the SysAdmin Team), the issue was resolved.
Here is the portion of the Desktop Client 12.4 CUM #3 readme that touches on the change made that's causing this issue:
"With this vulnerability fix, clock difference between client and server is supported maximum by 1 minute. If the difference is more than 1 minute, login will not happen.We suggest that ESP dSeries Workload Components should be clock synchronized."
In the Desktop Client's internal_trace.txt file will also show:
2025-05-22 12:02:24,238 ERROR Also, please verify ESP dSeries Server and Desktop Client machines clocks are synchronized
