The ESP connection to the server through web proxy is not supported, and fallback to SSL is disabled

Why am I getting this error and how should I go about debugging? I'm using macOS 10.14.6  and pulse secure 5.2.9 (1161)

Re: The ESP connection to the server through web proxy is not supported, and fallback to SSL is disa

Fallback to SSL option has been disabled on the VPN server, hence the Pulse Client will disconnect the connection. By default, Pulse Client will try to open up a ESP data channel with the VPN server, if it doesn't get any reply back from the server, it will fallback to SSL (TCP 443)

 

Please connect to VPN from a network where UDP-4500 traffic from the Client to VPN server is allowed.
