Backups failing due to SSL handshake timed out

[shomanjk]

I have been getting intermittent errors that backups failed, usually when transitioning between 4G and WiFi. However lately, it will not complete a backup at all (or much less often). I am seeing the following in the logs. It has been a few days since the last successful backup.

12-03 18:37 General error: Unable to connect (exception: com.fsck.k9.mail.MessagingException: Unable to connect, underlying=java.net.SocketTimeoutException: SSL handshake timed out)

Any resolution suggestions?

I'm running SMS Backup+ 1.5.10 on Android 6.0.1 on Galaxy S6 Active

#626 Seems to be a very similar issue to the above, just a different timeout error though.

I turned on Extra debug information and then ran a manual backup, here is the log...
