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.
