Hello!

I am using the machine app and my license allows the use of machine app (or should!). However when I deploy everything to my box, the Motorcortex service does not start (or it might start and exits early).

When I rename my license file (from license.lic to license_test.lic), the Motorcortex service starts and continues with no issues (aside from no valid license found error).

See attached. Things to note:

I start off by showing the error. The license is in fact valid but I also have these lines in mcx-lastlog:

bye-bye

Then I rename my license file and show that now the license is not valid but the lines I mentioned above does not exist in mcx-lastlog.

If the license file truly does not include the machine app, should the service should still continue running? And the license includes the machine app, is there maybe a mistake in this license file?

Thank you!

I tried to attach a GIF of the problem, then I tried a text file. Both options don't work. I can't paste it here either because only 65535 characters are allowed. So I'm open to opinions on how I can share more details about the problem.
