VPN service unavailable; reason: No assigned address

[Sachin Kulkarni]

Hello Experts, I have created a Devnet Sandbox and was able to connect using AnyConnect client. However after some time, I keep getting Unable to Connect and No Assigned Address on the VPN client. This error come very frequently and unable to use the Sandbox productively. Any help on this will be greatly appreciated. Thank you.

I have the same problem right now and using ubuntu/openconnect

Can anyone help before my session runs out?

I have tried with -v with openconnect 

sudo openconnect -v devnetsandbox-us-sjc.cisco.com:20171

For some reason that I still can't understand it is working now

we've tore down your VPN connection manually. Please try your openconnect again.

Thanks, 

I can confirm that the session has been reset

Received server disconnect: b0 'Administrator Reset'
Send BYE packet: Server request
Session terminated by server; exiting.

I have been able to connect back in with no issues so far.

Thanks,
