ZScaler blocking Tor and bridges in every way possible. Bridges not working.

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".
