After updating Reallusion Hub and upgrading to Character Creator 5 and iClone 8, I began experiencing persistent Server Connection errors. Here is the full situation:

Issue Summary

Character Creator 5 (CC5) cannot connect to the server.

Reallusion Hub also cannot connect to the server.

iClone 8, however, connects normally with no issues.

System & Environment

Operating System: Windows 11 Pro

Reallusion Hub Version: Latest (updated prior to the issue)

CC5 and iClone 8: Newly upgraded from CC3 / iClone 7

Troubleshooting Steps Already Performed

Turned off Windows Defender Firewall completely for testing.

Added all relevant Reallusion applications and executable files to the Defender whitelist (allowed apps).

Verified that the system has a stable Internet connection.

Restarted the PC and reinstalled Hub components.

Confirmed that other apps have no connection issues.

Current Behavior

CC5 shows repeated server connection errors on startup.

Reallusion Hub fails to connect to the server.

iClone 8 connects to the server normally, which rules out a general network or firewall issue.

Additional Notes

No VPN or proxy is being used.

This issue began only after updating the Reallusion Hub and upgrading to CC5.

CC3 assets imported into CC5 appear correctly, but server-side features cannot be accessed due to the connection issue.
