Strange host ID for academic license

When I run cvx_version to obtain a username and host ID for an academic license, I seem to get an invalid response. Here’s the output that I get with the input “cvx_version”:

As can be seen, I do have an academic license, and I attached the strange Host ID that I’m getting (by merely chopping off four of the leading zeros). The second host ID I’ve attached is the result of a previous installation from a few months ago on the same computer with the same network card. It pulled a valid host ID then, and I’m not sure why it’s having issues now.

I’m not the first to have this problem, and I posted on the other thread as well. Since I didn’t get a response, I’m trying to start a new topic to see if that will garner any assistance.

Does anyone have any suggestions on having cvx_version secure a standard host ID? Or are there any suggested references that might help resolve the situation? I apologize about the naivety of the questioning, but I’m a bit lost on these matters.
