Images not showing despite having HTTPS in URL in Email Editor

Hi there folks - I have been using Marketo for the past 4 years and have never come across this issue.

Oddly the images for me do not show up despite them having https in them. It was working just fine then on Apr 15 2024 it stopped working.

Now here is the strange thing. I checked my firewall and there doesn't seem to be any issue. I work in Canada so I thought what if I used a US address with a VPN service and using a US ip allowed me to see all the images just fine. So if I turn off my VPN and go back to my Canadian IP address, the images stop working. Any clue?

Here are the images of me using US vs Canadian IP

Here is also the image link I am using - https://go.restaurant.org/rs/078-ZLA-461/images/Webinar-banner.jpg
