Happened to me just now - I got a grey screen with “safari can not open the page because the network connection was lost”
I removed website data and then it was fine.
It's been one case of clearing the site cookies (on the day I started the thread) for me and no problem at all since. Opera, Windows.
Only use Tapatalk on my phone, haven't noticed anything other than the fairly longstanding Tapatalk issues (threads not remembering where you last read up to, etc).
