It looks like it requires a login? If so can you please send credentials to support AT jaksta.com with instructions so we can test for you, or please provide a valid url.
Could you also provide debug logs as per https://www.jaksta.com/support/windows/technical/jaksta-media-recorder/how-to-generate-debug-logs-6000009063
