Can you check and ensure whether the report.url is correctly configured to your domain/IP in the system parameters.

Activate developer mode, navigate to Settings -> Technical -> Parameters -> System Parameters, check the records and see, whether there is a record with key as report.url, if yes, check and ensure the value is your domain/IP.

If the key is not existing create a record with key report.url and specify the value as your url.

Sample:

Key: report.url   Value https://www.walnutit.com/
