Martijn Got Safari Can't Connect to the Server again. Bye longer Sublevel note, you will never see the light of day.

🏒 Lucian Marin I wonder why this is happening only on Safari.

Adam Douglas If it helps, I access Sublevel from iOS Safari (9.3.1) every day and I never have this trouble. What version are you running?

🏒 Lucian Marin Do you post from iOS? Sending POST over HTTP/2 on Safari after some considerable delay hangs the connection from server. It might have something to do with the way NGINX implements HTTP/2. Dropbox experienced some of these issues too while using Swift SDK (blogs.dropbox.com/...).
