Question

When i'm connecting to CompleteFTP from SyncBackPro application i have errors like this:

2017-05-23 13:52:10,251 ERROR [Session.41:Default Site:ESCAD_AUDI:212.185.xx.xx] site command failed MissingMethodException: ZONE
2017-05-23 13:57:33,753 WARN [Session.41:Default Site:ESCAD_AUDI:212.185.xx.xx] BeginAccept failed: Cannot access a disposed object.
2017-05-23 13:57:33,753 WARN [Session.41:Default Site:ESCAD_AUDI:212.185.xx.xx] Object name: 'System.Net.Sockets.Socket'.

What can i do?

Comments

Probably best to open a new ticket here, and attach a debug log showing the issue. I can tell you though that ZONE is not a standard FTP command, and isn't supported by CompleteFTP.
