I will try and sum up the best I can for fixing this issue.

To add nodes so you can connect to the network if default nodes aren't available at the time.
You can visit this page: http://www.presstab.pw/phpexplorer/FLT/nodes.php

This page will give you a list of nodes, just copy and paste them in to your
fluttercoin.conf file.

For linux just "nano ~/.fluttercoin/fluttercoin.conf"

For windows browse to c:\users\YOURUSERNAME\appdata\roaming\.fluttercoin \
It is possible the path above may be invalid depending on windows version.
Windows 7/8/10 won't recognize the file but you should be able to right click and open with -> notepad
From there just copy and paste the nodes from the above link.

Restart your client and wait minimum 10 minutes.

Any questions, comments?
