--------------------------+------------------------------
 When connecting to the Tor network on a network running the ZScaler
 firewall!, it ALWAYS gets stuck on bootstrapped 10%: Finishing handshake
 with directory server. I have tried all bridge types : scramblesuit, obfs,
 and meek. I have also tried running behind firewall with restricted
 policys. These ALL yield the exact same result. A few helpful details are
 when connecting to ANY website with SSL, even google, all browsers give a
 certificate error. Another note is before accessing any webpage besides
 google, a user must "login".
