Encryption now defaults to "Use explicit FTP over TLS if available"

[dkaiser0312]

In version 3.10.0.1 any existing sites defined in site manager
are now set to "Use explicit FTP over TLS if available" instead
of whatever settings were previously in use. To clear up the issue they must go toe Site Manager
and change the encryption back to the previous setting.

This is causing many problems as users can no longer connect to
sites that were previously defined and do not support encryption.

FTP over TLS is only used if the server actively says it supports it.

This is causing many problems as users can no longer connect to

sites that were previously defined and do not support encryption.

If this happens then the server isn't configured properly or there's a firewall or NAT router actively interfering with the connection.

To solve this issue, fix your servers, firewalls and NAT routers.
