@gmathis 

Is your reservation showing as active and set up in your reservation list?

You can check your ports are open TCP port 443 is required for SSL VPN with AnyConnect, UDP port 443 is required for DTLS over SSL but this is optional. Ephemeral ports are required also, the range is anywhere between 20100 and 20354 (you can see you had 20236). Disable firewalls on your machine etc.. If you can check via another ISP, such as tethering you mobile device to laptop etc...

Can we get your reservation# for troubleshooting?  You also can check:

- Is the reservation in "active" state

Sandbox will revoke VPN access once lab completed

- Have you connected the VPN before

The VPN session does not teardown in server side sometimes, which occurring VPN disconnected  abnormally. Please ask Sandbox team close it if you can connect before but not this time.
