I also experienced this issue and am just posting my observations about it.
If I attempted to connect via Port 80 using SSL, Alt Binz would freeze and require a forced close.
I believe this behaviour is caused by my ISP using a transparent proxy. I'm in Thailand, and the ISP proxy causes unexpected data to be included in the handshake on port 80, preventing connection. However, if I first connect to a VPN and then connect via AltBinz, it avoids the ISP proxy and AltBinz now works perfectly on port 80 with SSL, but only when using a VPN. Therefore if anyone experiences this issue, it may be due to an ISP transparent proxy providing unexpected data when attempting to connect on port 80.
