ecommscript-integrationapp.trustpilot.com refused to connect

[Juiliard]

Hello
I cannot access Trustpilot Settings, because of the errors mentioned below.
Trustpilot widgets are not appearing any more on my website https://juliard.club (they did worked for more then a year).
I can only reinstall module, which I did, but this did not helped.

Steps:

1. I have done a fresh install of Prestashop v 1.7.6.5 on Asustor NAS (fresh new NAS model used with all default settings: AS6602T)
2. successfully Installed Trustpilot v2.50.855 but when try to open module the following error received: Trustpilot extension is not supported on HTTP protocol Make sure you are running your website on HTTPS protocol.
3. after adding httpS to address (or activating option SSL on all pages) - another error message appears: ecommscript-integrationapp.trustpilot.com refused to connect

• similar errors appear on Safari, Chrome, Mozilla, Edge and even IE; checked on both: Mac 12.3.1 and Windows 10 systems
• the same errors on live site: https://juliard.club

Any advises?
