Handshake failure: TLSv1.3 early data?

And lots more similar overnight:

error:140E0197:SSL routines:SSL_shutdown:shutdown while in init, State:
TLSv1.3 early data

It seems some browsers open three to five sockets at the same time and
then don't complete SSL negotiation on all of them, just closing them
in various states.  

So not really negotiation failures.
