A refused connection and a timeout describe different connection outcomes. Refusal can occur when no service accepts the request at that endpoint; a timeout means the expected response did not arrive within the allowed period. Neither identifies the account status alone.
Verify the endpoint exactly
Check the scheme, hostname and port against the details supplied for the account. An incorrect port may reach no listening service. Avoid changing HTTP to HTTPS or adding a port by guesswork, because the server must support the selected endpoint.
Consider the network policy
A firewall or managed network may reject or drop traffic. Ask its administrator when appropriate. Do not disable all security software simply to see whether one player begins working.
Keep the distinction in the report
Share the exact wording, operation and connection type with support. A generic loading-spinner description loses useful detail. If the app provides no error text, say that rather than assigning a technical failure code yourself.
