When you arrive in a different place, you must first ensure that your computer can connect to the Internet correctly. Secondly, check the original connection mode in the software to see if it is correct. It is possible that it is originally a LAN login, and you need to log in directly after the field. Finally, take a look at the selected connection site and see if it is available in different places (try another site). In short, it is not a problem of GF Securities, but generally a problem of various network settings. Don't worry, a good check will definitely help. I wish you success!
