Why do I get 'Xpoda Service connection cannot be established' when changing companies in Studio?

This error typically occurs because the Xpoda Service on the target company’s server is not running or its port is inaccessible. Check if the IIS site and Application Pool for Xpoda Service are started, and ensure the port is open to external access (e.g., allow 40.118.18.65 through your firewall).
