No Machine on DevTerm

Has anyone else been able to run something like No Machine on their device? I am using an A04 with the most recent image on it, and I can install the software just fine, but when I try to access the DevTerm from another machine I get an error screen that tells me that I have to logout of the device. I will find a screenshot of the error after work today to attach, but I am looking for advice if anyone has encountered anything like this. Or if anyone can test the software out and see if they can use it successfully.
