I have set up a test SUSE box to test and can not get through BorderManager3.7 sp2 NW6 sp3
I use Craig Johnson's proxy config files, Tried turning TLS off and on, and added my Proxy server to the exclude list.

With the proxy server in the exclude list I get a URL /BM-login not found.
With the proxy server out of the exclude list I get the login screen but a connection is broken.
