Problem updating LIM from v22 to v24.2

Hi,

we are upgrading our Fortify LIM installation from version 22 to version 24.2, and are following the instructions in this document: portal.microfocus.com/.../KM000035098

This is a Windows installation without Docker.
The server where the LIM is installed has a default browsing proxy configured, while the LIM must use a different proxy to access the internet, reachable via http (not https) on port 80.

After installing and initializing the LIM, upon activation (i.e. after pressing the "ACTIVATE" button) we receive the following GUI error:

----
Error
The following error has occurred:
Internal server error
Error message detail
Http failure response for lim-test/.../server-license: 500 OK
----

Inside the file "C:\ProgramData\Fortify\Fortify License and Infrastructure Manager\logs\2024-12-10.log" we find this error:

----

What could be the problem and how to solve it?

Thanks,
