Snow License Manager is redirecting to home page when accessing something else like "Search for computers" or "Search for applications" etc.

The investigation might show that there are different requests in the HAR files that report a 403 or 404 error message.
When the request is working intermittently, it is potentially caused by more concurrent requests being denied.

Please investigate if "Dynamic IP Restriction" is enabled in IIS.
This can be the reason as to why different requests are failing every time you reproduce the issue.

The cause was due to "Dynamic IP Restriction" in which was activated in the customers environment with limits set to low which caused it to discard further requests.
