Zeos Query freezing program

I have a system that makes remote connection to a server with MySQL on the Web using Zeos, in some cases, where the connection wont oscillate, at the time of running Open in a query, the system freezes, does not display error and does not crash, the visual part of the system continues to respond normally, only the features do not perform any action, the system only works again after restarting. Has anyone had this problem, or have you seen anything like it?
