hi @igrr
I am use Arduino ESP8266 v2.4-rc2.
when I use MQTT to connect Server over SSL I got problem make client cannot connect to the server because not enough 3 steps handshake, some other network is working.
this is log when failed

when I tried another network and success with log:

where xxx.xxx.xxx.185 is my MQTT broker.
