CloudCache warning - Server fails to connect to CloudCache to back up or restore
This article applies to:
- OS: Windows, Linux
- Product edition: Phoenix
Problem description
The Phoenix Management Console displays an error message:
Server is not able to connect to CloudCache for backup / restore.
However, the CloudCache connection status appears green on the console. The CloudCache service also appears running and sometimes, the following message appears in the logs:
Could not connect to CloudCache server.
Traceback
The CloudCache logs contain:
{snippet}
[Errno 10013] An attempt was made to access a socket in a way forbidden by its access permissions
{snippet}
Cause
This issue occurs when the port 443 used by an application other than Phoenix Cloud Cache. There is a conflict of the port as Phoenix CloudCache also tries to use the same port for communication.
Resolution
- Run netstat -an on the command prompt to check the port usage. The command will list the ports in use.
- Check if the server has IIS role installed. Stop the IIS service if it is running. This will release the 443 port.
- Restart the Phoenix CloudCache service. This will resolve the issue and backups will resume successfully.
Note: Install the IIS role and Druva CloudCache on different servers.
