Hi @S J PE,

Does it happen on other browsers (Firefox, IE, TruClient Browser)?

Thanks for your response.

I didn't check with other browers, in our org using the Chromium browser only.

Hi @S J PE,

Can you check if below HTTP header exists in HTTP Response of your page (before executing the failed TruClient API step)?

Content-Security-Policy: upgrade-insecure-requests

You may check it with real Chrome (not TruClient Chromium). You can watch it in Chrome Developers Tools - Network panel (tutorial), or use some tools to capture HTTP data, such as Fiddler.
