Difficulty registering deployment

Once again I find that I can’t register a new deployment. There are no connectivity issues with the system. It resolves DNS, etc. It just will not register a deployment.

I’ve tried letting it create a new PBX Deployment ID, and tried specifying an existing, unused deployment ID.

I need to buy some modules and get this system configured. I’ve been trying this intermittently for 3 days.

Last time I had this problem six months ago, it miraculously started working.

Nothing in the log files, just silently fails…
