Checking connection errors
Proxy, firewall, and network settings that are not configured correctly can cause connection errors.
If you are using the standalone version, connection errors can occur if the firewall is not configured properly. Make sure that the firewall is configured properly as described by the procedure in Standalone software.
Refer to the instructions in Configure proxy authentication. Since not all apps support proxy settings, refer to the app documentation to determine whether the proxy is supported for the app.
If proxy and firewall are configured properly but you still have connection issues, have your networking team make sure that the network is configured properly.
