"Could not connect to Amazon S3 server"


The error message indicates that connection to the Amazon S3 server is not established. Any further operations with remote server will fail until reconnection attempt is made.


The error may be caused by connectivity issues such as firewall or antimalware whitelisting. Make sure that local machine can connect to the remote server—no firewall is blocking outgoing connections on the client, and incoming connection at the server.
