Storage Center Alert: How to Troubleshoot SupportAssist’s Phone Home Data Transfer Errors
Review any recent network or environment changes to make sure that they are not responsible for the connection issue. Typically, if SupportAssist was working and has stopped, something in the environment has changed.
First, verify that firewall settings allow outbound communication with ports 22 and 443 from both controller management ports as well as the shared management IP address. If web filters or proxies are utilized, confirm these ports are not blocked for all three management IP addresses.
If your network uses a proxy, verify that the Storage Center is configured to use the proxy server. If the proxy requires authentication, verify the username and password are correct and have not expired.
If none of these troubleshooting steps resolve the issue contact your service provider.
