After installing LMS, the URL needs to be changed. Examples are going from HTTP to HTTPS or vice versa and adding in a custom host header instead of using the server name with a custom port. Anytime the URL is changed in any significant way, you will need to run a utility to push the changes to the LMS database.
http://licensing.mycompany.com -> https://licensing.mycompany.com (the protocol has changed to HTTPS which uses port 443 instead of 80)
http://licesning.mycompany.com -> http://wslicensing.mycompany.com (the URL string has changed with the addition of ws)
http://myserver:12345 -> http://wslicensing.mycompany.com (using a custom host header changes the URL string)
The LMS database retains configuration information about the site. Changes to the site through IIS are not propagated automatically.
Contact Support at https://support.winshuttle.com to obtain the utility.
As per best practices its always recommended to do re-installation in case its fresh installation.
