License fails in Rasbperry pi 3

I have a perpetual license key and I am running Nuitrack on Raspberry pi 3.
And so I enter “nuitrack_license_tool” in terminal. And then I’m trying to activate the license on Raspberry pi 3 and I’m unable to enter the license code after the compatibility test finishes. The test finishes within a second without any errors, the terminal however does show two errors about SSL.

After enterinng “uname -a”, the reusult msg is following.

"Linux raspberrypi 4.19.75-v7+ #1270 SMP Tue Sep 24 18:45:11 BST 2019 armv7l GNU/Linux

Let me know how to activate my license key for Nuitrack.
