The client is disconnecting or some other error is happening to close
the connection before the SSL context is setup. The SSL-bump code in 3.4
and older does not handle that at all well.

If you are able can you please try 3.5 and see if the problem is
resolved. There was some timeout handling added there, but I'm not sure
if it covers this particular case.
