By default the QT wallet might not connect to the seed nodes properly on first try and you will find your wallet failing to sync it’s block chain with the network. It will appear to be stuck. Here is the fix.

Gracefully quit your QT wallet on your computer first. We posted a default file here on our Lynx Github Wiki that contains a file you can review. Copy and paste the gray part of the wiki article and save it as lynx.conf. Then place this file in the respective directory on your operating system. That path is specified at the top of the article. Then start your QT wallet again and sit back while it syncs.
