By default Noffle will time out the connection if it has to wait more than 30s
for the initial connection to complete or for a reply to a command to be
received.

You can change this timeout by setting the connect-timeout config file
parameter. The manual page is not as clear as it should be; this timeout
applies to more than just the initial connection.

In view of your large latencies, can I suggest you try setting connect-timeout
to, say, 120?

You can't force it not to switch to offline mode. Noffle take the view that if
the connection failed, something is pretty seriously wrong with your network
connection or the server, and it should take action to ensure it doesn't keep
pointlessly retrying. So it resets itself back to a mode where user action is
required to initiate more network activity.

It would also save the 'MODE READER' transaction and re-authenticating if the
upstream server required authenticating.

I'll put it on the TODO list, but it's not that easy to do given Noffle's
present structure.
