me too, tried everything, cannot sync either, it's been 2 days...
I test and shut down wallet and after restart it sync as normally.
So network is well.
edit:
There was something wrote about some china IPS blocks 4444,44444 port connetions.
So port 4444,44444 nodes you may cant use.
With first update I recommend dev may change port, so more secured/monitored clients can join in too.
Are you all in China?
