Problems with the license in terminals

Hello, recently I was installing samba in a new terminal, that version was 5.3.6 curiously this caused me problems with the database and the entry of the other terminals was damaged (because it had another previous version)

I had to update all of them to version 5.3.6 and since then I have had problems with the license, I have followed these steps:

Uninstall the license module
exit the market
restart samba
Delete key on 4
Install license module
restart samba
Login to samba
Activate license.

The problem is solved temporarily, it is a matter of 1 or 2 days and in the terminals it appears that I am using a trial version and finally the server also shows that I am using a trial version. I go back and apply the steps, it works again, but this problem is annoying.

Is there a way to fix this so that the license stays activated longer. (in the previous version this did not happen to me, it worked ok)
