Connect

With an open connection and no activity for more than 3-5 minutes, the connection falls off and breaks. When you try to continue, you have to wait 15 seconds until she realizes that the server is gone, then she will offer to repeat the connection. Then it will be installed again. And if you had open files - saving them again may fail, because they were opened in another session. And no buffer optimization will help you. That is why putu does not suffer from this?
Is it such a difficult thing to keep the connection?

Do you have keepalives enabled?

Do you have the latest version of WinSCP?
If you have, can you post details of the problem?
