What is your question?

Hi everyone,
following the instruction from this page, I tried to install the FdP on a remote Virtual Machine with Linux. At the beginning everything was fine and I was able to create a Data Point called "INFRAFRONTIER".
At the time of installation instead of an uri I used the VM IP since at that time the uri was still not available.
Now both when using the new uri or just the IP, the page is loaded but I got the message "404 not found" or sometimes "unable to get data" and for both in the terminal I get the following error message:
infrafiab-ready-to-go-fdp-1 | 2024-03-13 11:59:43,403 456549 [http-nio-80-exec-4] ERROR nl.dtls.fairdatapoint.api.controller.exception.ExceptionControllerAdvice - No metadata found for the uri 'https://VM-IP'.
How can I solve this?
