Hello,
Thank you for your inquiry.
Theoretically, it won't happen, because we have no limitation to the license application on the test server.
Below are my suggestions.
1. Please
apply the license by license key.
2. Try to compare the settings of the two servers and find out the difference which could cause the issue.
If it still bothers you after investigation, please share the detailed information of your live server and the IIS settings.
We would appreciate it so much if you could share some screenshots about the information we need.
Sincerely,
Jane
