Pulse secure "Unexpected IF-T/TLS packet when expecting configuration"

[Aiden Foxx]

I can successfully authenticate to a pulse secure network, but after
that openconnect errors out with:

I searched the filename of the last packet and found it was related to
some Juniper host checking software, for ensuring certain software is
installed. Is there any support for this in openconnect, or any way
around the issue?

Cheers.
