OpenConnect succeeds, PulseClient can install certificates but then is unable to find certificates

[sg]

On Ubuntu 16.04, following succeeds in establishing a connection:

openconnect --protocol=nc -c cert_stuff.pem -k cert_stuff.key -u the_user https://some.url.net/sub

Following reports success:

/usr/local/pulse/PulseClient_x86_64.sh install_certificates  -inpriv cert_stuff.key  -inpub cert_stuff.pem


But following fails with error message about missing certificate:

/usr/local/pulse/PulseClient_x86_64.sh -h some.url.net  -u the_user  -U https://some.url.net/sub  -r 'the-relam'

Would prefer to use PulseClient;  so how to establish a connection using PulseClient?

Can you test the GUI-based client?
If you specify the certificate in the command, does it work?
