License Error: Unable to check out EDEMGUI License, EDEM v2025.1

I am currently using the student edition of EDEM, and it has been working well for the last few months. I was running a simulation and midway through I got the following error, attached below. I was hoping someone can help me out, I have a University project due in less than a month and I need to view my EDEM simulation data.

You need to be periodically connected to the internet for the license heartbeat, we see that there was a link yesterday, does the error persist for you now?
