A few options:
Turn Enhanced Security on/off
Disable Enhanced Security
add site to trusted sites
Use Google to search for your answer.( content within this application coming from the website - Google Search)
This may work to ("Content within this application coming from the website listed below is being blocked by Internet Explorer Enhanced Security Configuration" when running Standard Reports (ibm.com)

This is because PAD is using a legacy method for signing in. It's not specifically for this connector only. If you signed out of PAD and tried signing in, you would likely experience the same.

What @365xMVP suggested is correct. There is no other way to resolve this. Please note that there may be several links you need to add to trusted sites. Check the specific site the error is listing. Every single time you add it to the trusted sites, the error will show a different site on your next attempt. You will need to do a few iterations of this before you get through the entire sequence. Then it should work.

Hi @opit

This error is because of the Excel online connector is trying to run a script to authenticate with your excel, so IE is stopping the script to run. The below is the mandatory setting you need to do, If those are disabled and not able to do then you need to reach to your admin and also them to do the below settings
