IntelliJ Troubleshooting

CodeScan Project binding updates gets failed

If the CodeScan update binding is getting failed, try disabling the VPN and antivirus, then try updating the binding again.
If the binding successfully updates, the error occurred due to antivirus blocking CodeScan. Add CodeScan to the list of allowed sites for the antivirus in use.
If the binding still fails, raise a Support Ticket, including the analyzer logs and verbose logs in the attachment.
