Hmm, I thought of an idea over my energy drink break (it's like lunch but less filling) =) - If you haven't, could you try logging in via Security Server IP instead of DNS on the View Client? If that does work, it's definitely not a permanent solution since the SSL certificate check (even if it is current and valid) will come back invalid. You'll have to make sure you allow the client to connect regardless of cert to test it.
As for which to remove to test I'd drop the blast entry, but I still don't see any reason for that to cause an issue. The flip-side though is that I can't directly see the configs so I may be missing something in my head. Also I haven't played with blast much yet and can't wait to get my hands on it. I checked it out before release about 8 months ago but I'm locked in an environment with no View at the moment. Still, I think blast can be configured to use the same URL just a different port, which is 8443 by default (correct me if I'm wrong on the same URL thing).
Hopefully the IP test works.
