Error fetching HTTPS response

[Zac Shepherd]

Hello,

I am unable to get an openconnect connection to work, it continues to 
fail on the last (?) step:
Refreshing +CSCOE+/sdesktop/wait.html after 1 second...
GET https://[vpn gateway]/+CSCOE+/sdesktop/wait.html
Error fetching HTTPS response

I've had this connection working for a while, not sure what has changed 
but need some help figuring out how to fix it.  Google searches have 
been unhelpful.

thanks in advance,
Zac Shepherd
